Lower Video Clocks - MSI Neo2 Platinum

[dwwalker14335]

I recently upgraded to a MSI Neo2 Plat 939 with a AMD 64 3200+ 90nm from a P4 3.4E system with the Abit-IC7 Max 3 875 system. I moved my UE card over, and it cannot clock nearly as well as it did on the Abit. Coolbits detects 500/1320, and it passes 515/1340 as it did on the Abit, but freezes with anything above 490/1300. I can run the card on the P4E system at 515/1320 easily enough, but not on the MSI board. I am suspecting a voltage drop somewhere on the MSI.

Here are the pertinent details:

AMD 3200 @ 2.75 GHz with 1.62V
PQI Turbo 3200 DDR @ 2.5-3-3-7 1T with 2.85V, 275 FSB
MSI Neo2 Platinum - tried BIOS 1.30, 1.36,1.37,1.41.1.51 with 1.51 appearing to be the best of the bunch.
Dual 120 GB SATA on RAID 0 - SATA ports 3-4 (locked)
OCZ Powerstream 520ADJ

I tried the enable/disable nVidia boost option. No change. I set the AGP voltage higher, just in case the BIOS reports it higher than reality.

Any ideas, input appreciated.

Sorry to say I don't think there is a solution. I had the excact same problem. I search all the forums I could think of, but to no use. I ended up selling my 6800 and buying a x800 instead. Just for comparison my 6800Ultra could do 475/1300 on my P4C800Deluxe-E and only 430/1200 on my K8N Neo2.

Dang! I'm getting K8N today O_O

[dwwalker14335]

OK, I will look at alternate 939 based motherboards. The NForce 4s are becoming available, but I will stick with AGP for now. Maybe the ASUS.

Sounds wierd, and its wierd if its true.

Does the lower clocks only happens to the 6800 or does it affect all graphics card?

[Lood007]

you did disable fast-writes, right?
That is a well known issue with the neo2 and the 6800's

[dwwalker14335]

Yes, I was aware of the fast writes. But, if I disable the fast writes, the performance hit is much larger than if I left them enabled with the lower clocks on the GPU. I may be able to get a higher clock, but it's a lot like a 2T memory timing to get a high FSB rate. Performance is hampered, either way.

And, it looks like the problem may be limited to the 6800 based GPU's. The x800 XT I used seemed to reach the same maximum clock on the Neo2 as the Intel 875 based board. So, if you have an ATI board, there may be less concern. But, I did not test fully with that card. The problem may exist with the ATI card as well.

I have an ASUS A8V Deluxe installed right now. I am rebuilding the system. I will keep the thread updated with any positive or negative performance results versus the Neo2.

Hmm I have a X800 XT PE, im hoping this isnt why ive been crashing :)

[MaxxxRacer]

i didnt notice this issue with my x800xt. I have only been hearing about it with the 6800ultra cards. Very wierd imo. Funny how ati cards seem to perform better on the nvidia system... the irony... (please no fanboy flames)

[jjcom]

yeah...bet Nvidia likes that lol It is kind of interesting to see how that works. Wonder why there is such a large drop in vid card overclock...mmm..

jjcom

[MaxxxRacer]

lol... why would they like ati cards to perform better than their cards on their system... seems backwards to me.. but hey everything is backwards these days...

[Dumo]

Samething happened to my 6800U and Neo2. Cpu, mem. and everything are almost maxed out no problem. 6800U, in other hand performed like 5900U :confused:
even with kinda high vcore/mem and EU bios mod. to 1.5V. As you can see in my 3d'01 score. Prolly with x800xtpe the score will be much higher. Something is not right, but I don't know.....what.

[jinu117]

X800XT PE in my case clocks in lower than on my 2ndary rig with P4. Something is going on here. (I mean by about 30/40mhz each on core and memory)
I gave up trying to figure out atm and will be jumping ship to NF4 once it becomes available from ZZF.

[jikdoc]

have you guys been disabling the ati/nvidia speedup option in the bios? it's a hidden option on the msi k8n neo2 plat board that you get to by hitting:

shift F2 simultaneously then alt F3 simlutaneously

the ati/nvidia speedup overclocks your card ~30 mHz which sounds about right with the numbers your mentioning. 490 + 30 = 520 on 939 board, 515 on intel. about the same. try disabling it and see what you clock up to

[dwwalker14335]

It sounds like the logical culprit. I have an ASUS A8V installed right now that I was trying out, so I will have to put back the MSI tonight. I think I turned off the hidden accel feature prior, but, then again, I did so many changes, I may have missed that on a BIOS flash (I tried all of the 1.30+ versions). I will verify tonight. Thanks for the info.

Hi jinu, hows the zippy compared to enrmx? :toast:

Just amazing. Enermax was no slouch but I was getting robbed about 180W of power since I don't have dual proc setup. (16 or 14a of 12v is dedicated just for 2nd cpu... word...)
This zippy... is HEAVY as in making that enermax feel light or any other PSU I had... (8+ lbs) and big... 22cm long. and... loud... (tornado level). I had to hack the PSU already and put fan on fan control. Even with fan running @ 6v, the PSU barely gets warm. Exhuast air is about 4c above ambient :)
As for 12v, 5v rails, prime 95 = idle... Can't ask for more than that :banana:
Haven't tried DMM rail checking while 3dmarking yet but I will when I bother to check 3.3v rail as well :)

Back to topic. I have speed up disabled all the time :)
