ASUS A7V266-E

[Izzyreal]

I have just recently installed one of these and am having serious problems with it. I installed it with a Coolermaster CPU cooler and fan Copper. AMD T-Bird 1400 mhz and 512 mb of DDR Ram. I have had it running at 1050 because it causes errors at 1400 its running from 45-50 degrees celcius. I cannot get it to run at any cpu voltage other than 1.8 vdc until I downloaded the most recent Beta BIOS. 1005e. Now it runs at 1.77 but still has random locks and will not even attempt to load Win 2K. Anyone else have this problem? Or a resolution please help.

you should try and get a better hsf than the coolermaster's. try something like the Swiftech MC462-A Rev.1 Socket A from coolerguys.com and make sure you are using good thermal compund like arctic silver 2 or alumina. 50 C is hot, quite hot so your really goning to want to bring those temps down to at least 40 C. i have the same board with duron 750MHz @ 1GHz with 256MB of DDR and have had no problems. just try bringing down the temps and see if that helps.

A cheaper alternative to Swiftech's MC 462, a copper hsf, is the MCXC 370, which is based on the excellent MCX 370 OA, an all aluminium hsf. It keeps my 1200 Athlon C between 88 F-98F. The MCXC 370 is mostly aluminium, but has a copper interface with cpu. Excellent cooling at half the price (and weight) of the MC 462.

At any rate, above post is correct: get those temps down and system instabilities will vanish. Good luck.

Thanks for the help. I have ordered a Wafer and some Arctic Silver 2 compound. For the time being I am running the CPU at a lower Mhz. I also installed an extra 80mm Case fan.

UPDATE : And an OCZ Goliath HS & Delta high speed Fan.

To an extent, I agree w/ those guys above. However, 50 C is still w/in normal operating range, and shouldn't cause serious problems. Make sure your mobo switches/jumpers are set properly, or better yet, use jumperless mode. Also make sure your processor is seated properly, cuz I have the same mobo w/ an Athlon XP, w/ factory heatsink/fan that runs at 42 C. Last, make sure that your powersupply is up to par, and AMD approved.

I was having lock-ups too and wrote Asus.

Here is a reply from Asus:

"Dear Sir, Please check the I/O setting on page 20 of the manual should be set to 2.65 volts. We have found that the setting has been at 2.8 volts and some of the memory will not work at this setting"

I changed the setting and I am still having the situation where a window gets frozen for 5 seconds. I also got a DVD and my creative sound card could not handle the speed of my board and was producing distorted digital sound. So I was told to increase the bios pci latentcy from 32(default) to 64. This resolved the sound problems, but the temporary window freezing still happens.

Any one have any idea?

Have you tryed the Beta Bios? 1005e solved all my instabillity problems. There is a newer version at ftp://ftp.asuscom.de/pub/ASUSCOM/BIOS/Socket_A/VIA_Chipset/Apollo_KT266A/A7V266-E/. 1006e is newer than what I am currently using.
