need advice w/ 2500 oc

Slimmy · Feb 25, 2004

Ok I have a lock 2500 barton. Thing is i have everything stock except the fsb to 200 for 11x200. Yet everthing i try i can't get it stable at 11x210.

I would think being able to run at 3200 speeds w/ stock voltage,

Tried upping the vcore to max (1.85) still prime fail right off the bat

tried upping vdimm to max still no help
tried memtimings of 11 3 3 2, 6 3 3 2 , 11 3 3 2.5, and 6 3 3 2.5 still not stable with prime.

try raising your agp voltage in the bios from its default to .1 above that. it tends to make your system more stable. also try changing the cpu interface option to its non-default setting, that might help too.

Just found out it is my corsiar xms w/ heatspreader 2x256
memtested it with stock timings and up the vdimm to max and memtest detected errors at 210 mhz think i am going to rma them

Shouldn't these sticks at least to 10mhz more that stock?

tried pull out one of my ram sticks and one won't do 210 and the other will

guess i will rma one

No PC3200 memory manufacture guarantees any overclocks. Your memory is rated 400 mhz (200 fsb) & you are running that fine. RMAing them is pretty lame in my opinion.

Thats like me buying a car with a four cylinder in it & returning the car because it won't go 200 mph after some exhaust tweaks.

Most wont do 3200 speed at default voltage...it takes my locked 2500 to run at 3200 speed (200FSB) 2v's to be completely stable at 2.2Ghz...

Now I can boot into windows using default voltage at 2.2Ghz, but it is far from stable...2v's is what makes it stable at 2.2Ghz...

i have the same problem with mine, my sig rig. I primed95'd it for 7 hours, stock voltage 200X11, no problems, lower ram timings, up it to 1.85 vcore, up the vdimm and agp voltage to their highest and up the fsb to 210x11 and it prime95 fails instantly, cant figure it out

its not good running your AGP voltage at 1.7 or 1.8v's for a long time...just like a CPU...VC's can only take a certain amount of voltage for only so long...

if 1.85 isnt doing it...then up the voltage more...you shouldnt have to up the vdimm voltage since you are already running PC3200...

This is the min. my 2500 will do and be 100% stable at 3200 speed (11x200)...I am running 1.6v on AGP, 2.6 on VDIMM...8-3-3-2.5
