Is ram holding me back?

Glaucus · 20 Nov 2008 at 16:18

Am I limited by ram?
Trying to overclock but when I get above 2.5Ghz it crashes or freezes when I run Blend in prime 95, but perfoms fine in place large FFts. In fact in large FFt's I can get over 2.8Ghz. Even at 2.8 cpu only hits 58C at full load

does this mean I have a memory error?

E6300
Asus p5k-e
2GB OCZ 6400

What appears to be stable although need to run a longer test
FSB - 355
Cpu Voltage - 1.3500
Divider - 7
Ram 2.05 (max 2.1)

Is that the maximum i can get? is the ram holding me back, is there some other settings I can try.

i had my 6300 running at 3.22ghz for 2 years, just recently has it started to go a bit wrong. Trying to work out what is going on.

at the moment i have my computer running at 2.8mhz.

your fsb dram isnt running 1:1, try running at fsb 1800 and ram divider at 2 - this will give you 800mhz dram.

edit - what cooler have you got, thats pretty high temps...

yeah change your divider on the ram down to 1:1 that should net you a lot more room to overclock the cpu

Cheers I'll give taht a try. Pretty rubbish akasa cooler.. But willing to go higher.

GinG · 20 Nov 2008 at 17:02

as stated, had to pull it back from 3.22ghz to work out what has gone wrong!

edit: added new image

hmmm......dunno whats gone wrong with the screen shot lol

I cant seem to see where to set dram divider?
and it will only let me select odd numbers for dram fsb

Glaucus · 20 Nov 2008 at 17:30

I see the fsb is related to the Dram fsb. If i set the fsb to 400 Then I can get ram 1:1..

Thanks guys seem to have it stable at 3ghz and don't want the temps any higher.

think I would need ram and better cooling to go faster.

Although do you have any idea how to stop it dropping the multiplyer? I assuming it's speed stepping or an asus version of the same thing.

yeah c1e stepping(speed stepping) in your bios, turn it off. plus you could always go higher than 52c, 65-70 is acceptable!

If you look at max temp it's 60 at full load after 12mins..

If I up it to 3.2-3.4 after a while it hits 64C and I get a black screen.

Also i don't think the ram likes it as I can't see a setting to isolate the fsb dram. Which means even 3.2 would mean 450Mhz

to be sure its stable i would run those stress tests for at least 5hours.

GinG · 21 Nov 2008 at 09:06

glad you managed to squeeze a bit more out of it!

as said though run the stress test for a bit longer than 12min!

My mate has one the of same E6300 and its getting very hard to get it stable
@3.0 even with 1066 ram he just got.

He is now getting a E6300 with a 1.25vid off the bay
That should overclock very well

EDIT here is a pic of my E6300 temps

1.14v is amazing for 3ghz on that chip i would have thought you would need at least 1.3 to be stable.
