An aside.... This is the board I posted about when I updated the bios to a

Running a sandy.. 250FSB @ 166MHz (5:3) HT4x @ 11x should equal 2750Mhz if I remember the AMD divider correctly and if your board supports that timing formula.

I goofed on that one... that 166MHz (DDR333) formula for AMD to run the sandy at 2750 will run the memory around 210-212. You will need to increase FSB to 270-275 with a Mult of 10.5x to get a memory speed of about 250 and 2750 on the CPU.

I got called away yesterday and didn't get back until late, won't be able to play with my PC until later tonight, here is the PSU model:

Skyhawk Power One GM470PC..... my model no. is superceeded and not shown on this page:

My PSU looks similar in spec to the new model GM520PC.

The NF4 chipset is known for some limits in the memory area. How bad it is limited I do not know (allot has to do with the motherboard) but I do know the memory should be able to hold 1T to at least 250MHz at 2.7v and higher at 2.8v. The only other possibility would be they mixed the BE-5 chips with the slower ones on the sticks (or one stick) and that would limit 1T use running 2.7v to below 245MHz. At 2.8v I would think they would still run at least 250MHz (remember, that

Thanks again NickN,

As a follow up on the 650 silverstone...  combined+3.3 , +5V 180W   thats actually kinda low for a 650 unit

In Silverstones case the smoking PSU is a design flaw.,.. they are aware of it. Your friend should contact them and have it replaced for free.

I cant promise a PSU upgrade will fix your stability.. but it won't hurt it when I look at what you are using, thats for damn sure

BOTTOM OF 32 Bit= (default value displayed)

MTRR= CONTINUOUS

If you are still online now, a quick question... I don't have these parameters, at least not in that format, is the "BOTTOM OF 32 Bit" a timing number I can equate another setting to, or is it a different parameter I do not have control over?

Also, if you have time, what do they do, are they critical?

If they are not available, dont worry about them because the system will default and never change them

BOTTOM OF 32 Bit allows you to see and set the limits of the memory map, something you would never use unless running 4 gigs or more and I dont know why they even made that available in the BIOS or the manual

MTRR determines the method used for programming processor memory clocks when using more than 4 GB of system memory. CONTINUOUS should be the default of less than 4gigs


If the memory slots do not support more than 4 gigs those items are useless anyway. There are new modules coming on the market that will supplly more than 1g each but when that board was made, they were not available to the commercial market


EDIT: apparently your BIOS is very different from the manual I got off of the Asus site for the A8N-SLi vannila

Ok, I'm not so worried now
