2.8E helpz

post #1 of 7
Thread Starter 
Im running my 2.8E Prescott fine in every aspect with the ram set to 333 MHz (before applying overclocking, 410MHz after) with the FSB @ 245 to get a clock speed of 3.4 GHz - and it runs exceptionally well - VCore is at 1.55-1.57 (1.6 CoreCell settings but it never runs that high, always lower) and getting stable temps of up to 58C under load running prime 95 - the biggest problem is that prime95 doesnt like something - My ram latency is 3-4-4-8 (5:4 FSB:RAM)[stock is 2-3-3-8] with the voltage at 2.75 - Im preparing to instal a couple of Nidec Beta V TA450DC's into my case to provide better cooling, but first I need to determine where Im running wrong at -

side note : To boot at 3.5GHz is a slow and jerky process, I dont know if I should increase my vcore anymore than 1.6 on this cpu - and every once and awhile the pc will reset @ 3.2 - but not at all at 3.4 - Im sure I could hit 3.6-3.8GHz but I need to know what the chances are of my cpu surving at a Vcore beyond 1.6V - and whether I should try to declock my ram slower to allow for higher FSB speeds without having unstable memory.

If you are throwing errors in Prime95 then your system is not "running fine in every aspect " either your CPU is unstable or your ram settings are not set properly. Are you running 2 instances of prime or 1?? You need to run 2 if you have an HT cpu.
I suggest running some memtest to see if the ram is throwing any errors. Download this program to test your rams stability.

Im pretty sure it is my ram - would it be better to try to keep it to stock speeds (DDR 400) and timings ?
I can't access this at home right now so if you could pm it too me after you post your reply would be great because I know threads get old and I won't be able to come back on after 12 EST 10/06/06 - Running cable through the house

Running the ram at stock speeds would probably rule out the ram on the overclocking part, but running memtest is the only way to find out if its the ram or not. A simple trick when overclocking a system, always start with the CPU first, find its max stable point and then tweak on the ram. If you must put the ram on a slower divider so be it, to keep it out of the equation while working on the CPU.

I have put it on a slower divider - in Bios it is set to DDR 333 isntead of DDR 400 - but once my FSB passes up 240 its back to DDR 400 speeds - and I don't think running it at 266 would really improve overall performance.

Well yeah when you overclock the CPU, the ram speed will go up with it, that is normal, your PCI and AGP clocks will raise as well unless you lock them. The point is the ram goes up when the FSB goes up, weather the ram is on a 1-1 ratio 2-3 ratio or whatever.

well how can I make sure everything is locked? I know a fair amount about overclocking the cpu and that the fsb = ram - or the 1:1 ratio - but Im just curious as to if I am skipping something or missing something ya' know?
