asus a8n32-sli slower than an8 deluxe??

Recently replaced my trusty old a8n-sli (running two asus en6800gt, 4 512 ocz platinum mem, and an fx 55) with the afore mentioned a8n32 board... (The a8n-sli wasn't so trusty after all, as its northbridge fan quit, frying the surrounding circuitry.)

Now to the crux of the issue: Prior to this MB replacement I was getting in the neighborhood of 9700 3dmark 2005 scores. Not overclocked (by more than 5% anyway).

Now post-upgrade (not over-clocked at all) I can barely get a 3dmark score in the 9100's.

I am using the latest Nvidia reference drivers for the graphics and the MB, and BIOS is up to Asus' latest version.

(Also, my CPU fan seems to run hotter, (57deg. or so, prior only got up to the mid-40's... ) But I put this down to the cpu xfer and plan to do a clean-up and re-smear of some good silver paste this wkend...)

Any clues? Any similar results?

Hi Croc,
Since last August had two A8N-SLI fans fail, one after the other, luckily with no burnouts and managed a sraight exchange on the last to A8N32sli.

Have no case fan, and have one side pannel removed. Temps are:
CPU 31c, Chipset 38c, HD 34c, (& Local 30c & Remote 34c, whatever they are for?)

I use Cool & Quiet with the "Automatic Fan Speed" ticked at the Monitoring program "SpeedFan".

The CPU Fan Speed modulates around 1205 rpm.

I never did 3dmark, but will try and come back to you.

I posted this below for help, but no answers. Do you happen to know anything about it?

1. Trying to Overlock my PC.
Has anybody had similar problem of Clockgen for nF4 (CG-NVNF4)?
It seemed normal with AN8-sli mobo, but after mobo exchanged for
A8N 32 sli, ClockGen comes up corrupted and unusable as per foto.
With / without firewals.
Redownloaded & un/reinstalled it several times.
Get Values were applied.
Any help appreciated.

2. Also, Tried to Overlock in Bios but I cannot find HTT values to change in my present AMI BIOS:
64-1009-009999-00101111-121405-C51G.

The previous A8N-SLI mobo had PHINIX Award BIOS and could find it there.
Do you know if I can change to this Bios on A8N 32 SLI ?.
Many Thanx, luke
PS. what are your PC's specs?

I have never used the CG-NVNF4 utility, but used to use the NVIDIA supplied OC tools NTune and NPerformance... Neither of them work any more either.

Seems that we are now stuck with OC'ing by the book. Oh well...

My fan never runs that slow, (nor my CPU temp) but then you didn't say what CPU you were using. I use 4 case fans, two in and two out, plus the pwr supply fans, so airflow is not an issue to me. Noise is, so my case is sound-proofed as best as I could.

OK,
I thought over 50c you thought was hot, I have mine to shout out at 50c.
My Fan speed is modulated by the Cool & Quiet & the "Speedfan" program, spins up when Temp rises, to keep it around 30c.
You can hardly hear it running
at:- http://www.almico.com/speedfan.php

CPU is AMD 64 3500+ (Venice 2.2ghz)

Would you be kind enough to try it and tell me if it shows as foto below?

You will find it here:- http://www.cpuid.org/clockgen.php
and go down the list to download this CG-NVNF4, for "nVidia nForce4 SLI" A8N32sli.

It will not hurt your PC, it only shows you the verious CPU / Mobo settings by clicking "Get Value" (while F1 gives Help) running , used for overclocking, that your PC has in the Bios real time at that moment.

It is a Windows utility, to set the various values at small increments using sliders & fine tuning, then click "Set Values" to alter the Bios ones within windows and see the degree of Overclocking you achieved real time, without having to shut the PC, bootup to the Bios apply values and back again to see results a number of times.

It is made for beginers, to avoid the dangers of fidling with the Bios.

At any time you can boot to Bios select defaults and you are back to square one.

It has the facility to save your overclocking values, and bootup to normal or choose them if say your flight simming.

It worked on my A8N-sli as the left one in foto below, but not on the 32 sli.
The midle the corrupted one is in the 32sli, plus the Speedfan. Luke.

Since previous thread, after a couple of B...up with failed bootups & restarts, I altered the Bios items 1, 2, 5 & 10 only plus all the [AUTO] to [Manual], rest are defaults.

PS. Clockgen sliders, (although corrupted & useless I use it to see correlation of the various values) taken to CPU 2422,
with these showing up on their own: HTT 220, Mem 110, PCIE 100, PCI 36

CPU Heat sink, Ram, Chipset & pipes were cool to the touch, 6600gt was warm.

PS. I do'nt know if foto cames out clear, but this raised the CPU speed to 2.419ghz, from 2.2ghz

And these to day raised Cpu spd to 2.57mhz (15% Oclock frm 2.2).
