SP1 for Vista is TLB override KILLER!

[Cooper]

It still doesn't change the fact that it (SP1) changes the patch workaround in both bios and AOD. AFAIK the only way to get your performance back is to use Sam's patch.

Sandra and winrar shows the same results. No performance hit. What else you need to change?

[KTE]

No problem Cooper.

Yep, anything memory intensive will show the Patch enabled/disabled very clearly. I used WinRAR from the beginning to cross-check because it was highly memory intensive across all cores and shows such cache/memory fluctuations on CPUs clearly. That's how we tested and found out that only the first core Patch was being disabled by many early BIOSes too, and exactly why better BIOSes and tools were later created mitigating these problems.

Cooper I haven't tried the SP1 on my system, I'm happy with it as it stands so I don't want/need to change it.
However I heard a whisper on the fact that SP1 is enabling the TLB patch so I googled it and there are threads everywhere telling people to beware of it.
Maybe your motherboard is not suffering from this but a lot certainly are.
I will be interested to hear the result of your testing.

When I searched for the problem everyone was using RC versions of SP1 so the final version might not have this workaround on it, but I don't know for sure either way.

[dr_drache]

AFAIK, it does enable the TLB fix.

and for staying away, i wouldn't suggest that, it's a very good upgrade overall, I personally suggest going SP1, and then using sam's tool.
it sucks a bit yea, but if you shyed away from an extra step, you wouldn't be on this forum...

[KTE]

Guys,
On your systems you have the Patch being enabled (as was mine with SP1) but Cooper said on his it's not doing so since the performance metric he's using is the same and performance is also the same. Surely something is amiss or different here.

Vista should give plus 1200KB/s WinRAR. With the patch enabled, that's not possible, so that's all you really need to tell if the patch is enabled or disabled... or just check the relevant MSRs.

[Daveburt714]

I could be wrong here KTE, but earlier Cooper said his Bios didn't offer the option to disable the TLB fix. If his Bios version has the fix built in he would never notice a slow down from intalling SP1.

It is DEFINETLY there! And like many others, the only way I've found to get the performance back was by intalling Sam's fix...

Try Sam2008's fix Cooper, I'd be willing to bet you'd get a pleasent surprise.

[sam2008]

The best way to check whether TLB is enabled, is the one as mentioned by KTE: benchmark WinRAR. If you get anything less than 1200kB/sec with your phenom, it is pretty sure the TLB is enabled. Try that out Cooper.

[Blacklash]

I put SP1 on my 9600 rig and lost 300pnts on the CPU portion of 3dmark06. Meh.

Well this thread has me a Tad concerned Not only have I just ordered a Phenom but I have just ordered Vista as well and I need to start using Vista due to work so does this SP1 Release only affect certain Motherboards? And whats this Sam2000 Fix I am hearing about please .

It affects Phenom CPU.

And whats this Sam2000 Fix I am hearing about please .

testing now

i won't be using sams tool - rapidshare is filtered in the office :/
btw can anyone tell me how on earth do i disable the tlb errata fix on dfi 790FX board? It took me half an hour to figure out the setting on Asus M3A32 board...

asus has option under CPU menu, and DFI under memory tweaks and timings... scorll down

[Cooper]

Thanks, found it

[Cooper]

Well as the OP stated SP1 does overrides tlb settings in the bios and aod on asus M3A32 MVP and DFI 790FX boards.

good job MS...

[macci]

Please try this:

1) uninstall AOD you might have (also delete the AOD folder from ProgramFiles, back up any profiles you might have)

2) install 2.0.17 (LINK)

3) replace engine.dll with the attached one

This should:

A) re-enable TLB properly on B2 CPUs
B) fix the "no AMD CPU detected" bug which can be seen on some systems running Vista

[sam2008]

Here is the one of the early console versions of the TLB tool. The GUI version are too bigger (>200kB size limited by the forum) to be uploaded here.

Macci do you know when can we expect new BIOS from mobo makers that'll implement proper override of fix applying?

Honestly sam's solution is for now only viable option 'cos it's suitable for applying override at the Vista startup, a non option for AOD. I for example just don't want to startup 16MB 32bit app each time Vista loads…

[Cooper]

I believe new AOD will fix the issue.
Thanks macci for advice. Will try this tomorrow.

[sam2008]

Actually, the AOD version 2.017 posted above actual solve the TLB problem even without replacing the engine.dll file. I have tested on a vista x64 sp1, it indeed applies fix to 4 cores unlike previous version.

I believe new AOD will fix the issue.
Thanks macci for advice. Will try this tomorrow.

[macci]

yup, engine.dll fixes the "no AMD CPU found" issue that can occur w/ 2.0.17 on some Vista systems running Phenom

[Daveburt714]

Thanks Macci!

That fixed all the problems with AOD.17 including the No AMD CPU.
And as was said earlier the Turbo button now disables the TLB fix on all 4 cores..

[Cisco Kid]

Okay guys I am thoroughly confused.

Just freshly formatted

Ta770 A2+ Biostar board and Vista 32 bit

Onboard Lan Boot Rom is enabled in bios, I am running rebel havens 228 tlb bios. Does this fix disable the patch or do I need to d/ Sam's tlb patch and run it, if so do I leave onboard lan rom enabled or set to disable and just use the tlb exe disable patch?

I had a beotch of a time with XP SP2 somehow my system was halfing my 9500 multi even with patch enabled something was forcing cnq to run even though it was disabled and with a bunch of help from other forum members I was unable to solve and am hoping this format fixes my B2 issue

Last does AOD work on 770 chipset?

[Brother Esau]

macci does this engine dll apply to fixing the TLB Overide issue with SP1 in general or is this only applicable for Overclocking Phenom through AOD???
In other words can you manually overclock Phenom through Bios and this will work as well even if you do not use AOD for overclocking of you're system but its installed anyways???

[Daveburt714]

Hey Brother E, I know you didn't ask me but I was online so thought I'd answer ya...

I'm 99.9% certain that the engine.dll only applies to AOD overclocking, and fixes the "No AMD CPU Found" problem when using the new version (2.0.17).
The Turbo Button on the new AOD does work fully though, ie: disables the patch on all 4 cores...

It takes a few minutes to settup, but AFAIC Sam's patch is still the best way to make sure the fix is disabled at boot...

Hope this helps man...

[KTE]

Guys;

If you start AOD, hit the Turbo mode button, the TLB Fix with whichever method at boot will go off.

As for the slowness... you can just edit the files and only have one tab that you need load up, that speeds things up quite a lot (what I do).
