FINALLY! Its running stable(asus A7N8X) but.....

[Skiguy411]

Well I finally got this ASUS A7N8X running stable(run games without quitting and havent seen a BSOD yet), but I had to set my memory frequency at sync and my CPU at 133. So instead of getting the 2600+, Im getting 2000+. Is this a heat problem with the CPU or what? How can I get it running at normal speed? Whats the diff. between "Sync" and "By SPD in the memory frequency?"

Thanks

I'm sure someone else can answer this better than I.

"BY SPD", as I recall, referred to some kind of setting in the CPU
that your motherboard reads to determine clock and frequency settings.... kinda like plug and play.
I think the intent was originally to lock someone into a speed.
I think SYNC allows you to choose the settings yourself, thus allowing you to overclock.

Check your motherboard manual. It should offer some explanation on this.
Or perhaps someone else can explain more (or correct me)?

On this particular motherboard the terms sync, by-spd, and user refer to the following:

by-spd - means that the BIOS will adjust the mem frequency according to what the SPD on the RAM tells it, that it can run. This is independendent of other factors concerned.

sync - takes the reference for setting mem speed from the CPU FSB and 'syncs' it according to whatever that speed is. (i.e. - a 133 FSB CPU = a 133 mem clock)

User - allows the user to set the values independent of whatever other values are present.


Ski - what version of the BIOS are you using?

I am using BIOS version 1001.G

I called the tech support guy and he said that I have to use DDR 400 to be able to use the Athlon 2600 at its normal speed. Right now I have ddr 333. Is true? Do I really need to get ddr 400 for this athlon to run at normal speeds?

What's your cpu's multiplier? The 2600 is supposed to run at 2.13ghz with a fsb speed of 166mhz. If your fsb speed is at 166mhz then set memory to sync. Then it'll be running at 166mhz also which is ddr 333. If you use 80% then the cpu fsb will be at 166mhz and the memory will be at 133mhz. If your cpu is at 133fsb and is at 2.13ghz then use 125% setting to get the memory at 166mhz.
Set your memory timings at active precharge delay 7, ras to cas delay 3, precharge delay 3, cas latency 2.5
Those settings are usually most stable. Allowing you to run the memory at its fastest.

Ok. The computer runs fine when the CPU is at 166 and the memory is at 80% (resulting in 133). It is unstable when the memory is at 166. 133 is the same as DDR 266 correct? The memory is rated at DDR 333, so this means there is a problem with the memory, right ?

Yep memory problems. What brand of memory is it? Check out the part number make sure you got pc2700 not overclocked pc2100

 

[Skiguy411]

Its generic brand. Good thing I ordered the 2 sticks of Corsair pc 3200 ddr 400. That shouldnt give me too many problems....

still waiting for memory?

 

[Skiguy411]

Ya I ordered it on wed..... should be here next week. Too bad ill be at the gator bowl in Jacksonville, Fl to watch my NCSU wolfpack play! but anyways I am hoping that will speed my computer up just a bit. not that its fast enough already......

GO NCSU!!!

For the record, I got the DIMMs from Newegg, they are indeed v1.1 modules.

For the record I have a 2700+ running on the asus a7n8x at 166 fsb. i think the memore is set at by speed cause i have old corsair 2100 ram in it. i'm gonna be ordering some new ram next month so i won't be able to test higher ram speeds till then.
