Chkdsk bug in Windows 7 RTM Build 7600.16385/16399


Recommended Posts

Well the appropriate guys at Microsoft have been notified of the issue, so rest assured that they are looking into it. But if it really is a driver issue, well, that's going to (rightfully) be the hardware vendor's responsibility.

No, not a showstopper. Kind of like the old Marx Brothers joke: "Doc, it hurts when I do this..."

"Then don't do that!"

I'm pretty sure I can go a day or two without running chkdsk until a patch is applied.

BTW, is this present in both x86 and x64?

This issue is present on non-Patched 7600.16385 and Patched 7600.16399 builds, also on Windows Server 2008 R2, both x86 and x64. My big concern if you read the main post now it is also present when booting from the DVD in WinPE where majority of the IT/PC Repair Industry would go to fix a clients computer.

Based on my finding that it is also present when booting directly from the DVD I would say chipset driver issue or not this should not have happened. Also, if it is a chipset drive issue... Why do all 3 of my computers that have Vista on it with the same drivers work fine using chkdsk yet Windows 7 has such a problem?

This is probably only a bug if the BSOD happens, otherwise I'm sure while they were developing it they knew of the huge memory consumption.

The /r command option says the disk must be locked, so maybe you were running a programming that tried anyways and poof

Nope, when the disk is dismounted all handles trying to access it are closed, essentially the thread is just killed off. Besides, that would cause high memory usage in the process trying to access the disk, not chkdsk itself

The /r command option says the disk must be locked, so maybe you were running a programming that tried anyways and poof

Yeah - as Frank Fontaine says, not applicable. I created a brand new 24GB volume in my VMware 'session', copied some random data to it (SQL Server 2008 installer) then dismounted the DVD image and ran the chkdsk. Nothing would have been using that data, but it still insisted on clearing any locks to the filesystem before it attempted to run the check.

I'm not sure it is a bug.. I'm running it now and it definitely didn't cause a BSOD.

All of my ram is not being used.. I'm hovering at 80% ram usage.. so the fact that it doesn't take up all of your available memory would seem to indicate that it stops short intentionally.

I'm willing to lay money on it being some kind of bug. Why would the behaviour of the application change so drastically and with no discernable benefit (quite the opposite!) between Vista and Windows 7?!

This seems kinda odd, why only with the /r command? And if it was a true memory leak you'd keep losing all your memory, I don't think it'd stop at some point/percent. And you wouldn't get it back if you close the app either would you? Don't memory leaks just take it all and never give it back even after, so you have to restart to get it free? That's how I always understood it.

I'd agree, it is definitely a bug. There is no plausible reason that I could come up with for it using so much memory. For anyone advocating it loading data into memory for performance reasons, just think about it for a second... the /r switch is used to check for bad sectors, a check which would be pointless and invalid if the data where preloaded into memory

Some more interesting info at another forum which, for some reason, Neowin won't let me link to (edits the url to include << spam >> tags!) - anyway, the guy posted this:

chkdsk /f seems to use 5MB of memory (at peak) for every 1GB of disk space you check (tested on a couple drives - example: a drive with 300GB of data uses 1.5GB of RAM

chkdsk /r seems to use memory equal to the amount of files on the disk. If I put 2.5GB of files on my USB flash drive and use chkdsk /r, it uses 2.5GB of memory by the end of stage 4 (though it stops increasing when you hit stage 5)

He also confirms that this only seems to occur on NTFS (not FAT) and that this appears to be a 64bit only bug...?

Surprisingly build 7600.16399 is faster than 7600.16385 on cpu operations. Confirmed with faster boot and playing a "heavy" cpu game. As for bugs, I still can drag the locked taskbar to the top by performing this: first, right click on any taskbar icon to open the jumplist then drag the taskbar up a little and it will move to the top. Another bug is when the taskbar is on top, if you do right click, the jumplist will have incorrect top position, but if you drag the jumplist, the top position limit will be the right one.

Heres a couple things I found sad.

1. Those 399 build updates are not official, unless its on Microsoft update or a official announcement is made, I'm not touching them.

2. Microsoft hasn't even mentioned anything about this officially yet.

3. According to Microsoft the RTM build is still coming to MSDNAA today, no mention of a show stopper or recompile etc.

4. This is not a chipset issue, chkdsk uses too much memory. And the 399 unofficial fixes do not fix it. When something is broken on all versions of different hardware, its not the hardware's fault, its the software.

1. They are. Never heard of an unofficial hotfix from MS.

2. Not publicly. Why would they? They could potentially harm their sales by going "There's a big bug in our final product."

3. Of course not. Again, why would they? Not everyone has the issue.

4. It has been proven.

Has anyone been able to post this on Microsoft Connect? They dont have a public channel for Windows 7? This should be resolved as soon as possible!

Connect is closed to bug submissions now for Windows 7.... have to get to MS other ways now, anything that goes to connect wil get to no one

    • AMD RX 9070 GRE AI, Blender benchmarks vs 9070 XT, 7800XT, Nvidia RTX 5070, 4070 by Sayan Sen Earlier this week, we shared the first part of our review of AMD's new RX 9070 GRE. It was about the gaming performance of the GPU, and we gave it an 8 out of 10. As a follow-up, similar to how we did with the 9070 XT and non-XT, we are doing a dedicated productivity review for the RX 9070 GRE as well, where we compare it against the 9070 XT, 9070, 7800 XT, as well as Nvidia's 5070 and 4070. This will include AI, rendering, compute, and more benchmarks. AI performance, especially, is a very important metric in today's world, and AMD also promised big improvements thanks to its underlying architectural improvements. We will be pitching it against the data we already have for the RX 9070, and RX 9070 XT, but also the Nvidia 5070 FE, MSI GeForce RTX 4070 VENTUS 2X 12G, and Gigabyte Radeon RX 7800 XT GAMING OC 16G as they are in a similar price class, but also because we do not have a comparable 5060 Ti card lying around here that we can compare it against. Before we get underway, this is a collaboration between Sayan Sen and Steven Parker, who lent me his test bed. Also, there was no editorial input from AMD. First up, the specs of the RX 9070, 9070 XT, and 9070 GRE, which were given to us by AMD: Radeon RX 9070 GRE Radeon RX 9070 Radeon RX 9070 XT Boost Clock: Game Clock: up to 2.79GHz up to 2.20GHz up to 2.52GHz up to 2.07GHz up to 2.97GHz up to 2.40GHz Stream Processors 3,072 (48 CU) 3,584 (56 CU) 4,096 (64 CU) Ray Accelerator 48 56 64 AI Accelerator 96 112 128 ROPs 96 128 Texture Mapping Units 192 224 256 Memory 12 GB GDDR6, 18Gbps Clock, 192-bit Bus 432 GB/s 16 GB GDDR6, 20Gbps Clock, 256-bit Bus Effective Memory Bandwidth: 640 GB/s Infinity Cache 48 MB (3rd Gen) 64 MB (3rd Gen) Card Bus PCI-E 5.0 X16 Output 2x HDMI 2.1b 2x DisplayPort 2.1a Power consumption 220W 304W Recommended PSU 650W 750W Slot width 2x 3x Price (SEP) $549 $599 As you can see from the specs above, it is less than the standard RX 9070 in every way that counts, except for slightly higher Boost and Game clock speed. Design Moving on, the RX 9070 GRE we were given is an XFX Swift triple-fan, dual-slot design with two 8-pin connectors. At 30cm (self-measured), it will fit in most systems easily. There is no RGB either. The AMD Radeon RX 9070 GRE by XFX from all angles. Test system Our test system consists of the following: Lian Li O11 Dynamic Mini V2 Flow (Amazon|Newegg) ASUS Z890 ProArt Creator WiFi (Amazon|Newegg) Intel Core Ultra 7 270K Plus (Amazon|Newegg) Thermal Grizzly KryoSheet - 44x37 (Amazon|Newegg) 2x 16GB G.Skill Trident Z5 RGB (7200 MT/s in XMP) (Amazon|Newegg) Sabrent Rocket4 Plus 2TB SSD (Amazon) Windows 11 25H2 (Build 26200.8246) AMD shared a press driver based on the recently released Adrenaline 26.5.2 that we were required to use. We now move on to our benchmarks. First up, we have Geekbench AI running on ONNX. For some reason, the 9070 GRE does exceptionally well here in both half-precision (FP16) and single-precision (FP32). It manages to beat the RTX 5070 and RX 9070 non-XT, and is only behind the 9070 XT. Since Geekbench runs in short bursts instead of continuously hammering the graphics card, it seems the GRE's faster boost clocks are helping here. Next up, we move to the UL Procyon AI test suite, starting with the image generation benchmark. We chose the Stable Diffusion XL FP16 test since it is the most intense workload available on Procyon. The Nvidia cards do very well here, as even the 4070 out-muscles AMD's best fairy easily. The positive thing about the GRE is that it gets quite close to the 9070 non-XT in this test; this indicates that the VRAM does not play a very big role here, as SD XL relies on float16 (FP16). So this is something to keep in mind again. If you wish to work with float32 AI workloads, graphics cards with larger than 12 GB buffers would likely emerge as victors. Regardless, the gains are still massive on AMD's 9000 series compared to the 7000 series. Following image generation, we move to the text generation benchmark. This is one test where the 9070 GRE struggled, quite a lot. It seems that the 12 GB VRAM and lower memory bandwidth of the new Radeon 9070 GRE are hurting it quite a bit; the split is massive, especially in a test like Llama2, which packs 13 billion parameters. As such, in all the tests, the 9070 GRE is the slowest of the lot. Next, we tried Blender, and here the AMD GPUs were beaten by Nvidia. Rendering is something the Green team has always had a lead over the Red side, and it has not changed so far. On the positive side, though, the 9070 GRE shows significantly better results than the 7800 XT, which means AMD is on the right path. Catching up to Nvidia, though, will require a lot more effort. And we hope HIP and ROCm can keep improving. Wrapping up AI testing, we measured OpenCL throughput in the Geekbench compute benchmark. The RX 9070 GRE alongside the 9070 did not fare well here at all, even falling behind the 7800 XT. Interestingly, even the RTX 5070 could not beat the 4070 on OpenCL, so perhaps this suggests that OpenCL optimization may not have been a priority for either AMD or Nvidia in the modern era. Conclusion We reached the end of our productivity performance review of the 9070 GRE, and we have to say it's a mixed bag. Unlike the 9070 and 9070 XT, the GRE excels in some areas while losing ground fairly easily in others. Similar to how it happened in gaming, any time the card's memory subsystem gets hammered, it tends to fall behind the others. This was the case with text generation, wherein we saw the VRAM sometimes hit its maximum available 12 GB of usage with larger model sizes. So what do we make of the RX 9070 as a productivity hardware? It can certainly be used, but you have to know it has its limitations. For those looking for a GPU that can deal with more, AMD recently unveiled the Radeon AI PRO R9700, which is essentially a 32 GB refresh of the 9070 XT with some additional workstation-based optimizations. On a similar note, the new Ryzen AI Halo platform is something you can consider if you want to set up a local AI processing station. Considering everything, we rate AMD's Radeon RX 9070 GRE a 7.5 out of 10 for its productivity performance. Price is less of a factor for those looking at productivity cases compared to those considering the GPU for gaming, and as such, we felt it did quite decently on many occasions and can be handy if you need a 12 GB GPU and, for some reason, don't want to get Nvidia.
