help advice on o.c e5200

[bobreece]

i have a gigabyte ep43-ds3l with 4gb corsair ram 5 5 5 18 and e5200

i currently have managed to oc it to 3.6 witn 360fsb x 10 1.36vcore idel temps never over 53 even with ibt running.

what i need to know and help with is

is it easyer to get a higher oc with a lower fsb?

do you think i could put more vcore throught it and be safe?

and if i keep my current oc i can either have my ram running @ 864 5 5 5 18
720 (i think it said maybe a little more) with 4 4 4 12 which on would be better?

I got to 3.85ghz stable (see sig for settings). I could get to 4ghz, but it would fail prime after an hour or so. didn't fancy going any higher with the vcore

360fsb is about the limit for me too. the e5200's don't seem to like going much above this...

Just got an E5200 + cheap mobo ... can only clock to 2.7GHz It's for the kids so don't really matter but I may just get a decent MATX clocker board as it bugs me knowing all that power is going to waste (Cbeebies web site will be even quicker after that one!)

i have tried 3.85 but carnt get stable can you answer the questions i put guys

1: is it easyer to get a higher oc with a lower fsb?

2: do you think i could put more vcore throught it and be safe?

3: and if i keep my current oc i can either have my ram running @ 864 5 5 5 18
720 (i think it said maybe a little more) with 4 4 4 12 which on would be better?

can a mod move this to the overclocking section just realised put it in wrong place guys sorry

1) Yes. Use the highest multiplier you can.

2) Yes. Up to 1.45v will be safe, assuming your temps are OK.

3) Usually the lower latency will be better - in this case 720 @ CAS 4 (this is ~ 11ns - i.e. 4 x 1000/360, as opposed the other setting you give, which is ~11.6ns -i.e. 5 x 1000/430). BUT using a higher multiplier on the memory generally lowers the timings on the northbridge (aka MCH). The timing to watch for is tRD - this can be more significant than the memory settings. Use Memset to see what the current "Performance Level" is - this is the 'standard' name for tRD - lower is better, as with most timings.

In short - my money would be the 864 memory option giving you better performance because of the lower tRD from the higher memory multiplier. It's not going to be light and day between them and you'll have to try them both and see.

Bob - Did you have to change any other voltages in the bios to acheive this or only vcore?

2) Yes. Up to 1.45v will be safe, assuming your temps are OK.

What temp would you say is safe? (under load)

I might try bumping the vcore of mine up a little more to try and hit the magic 4ghz

upped the fsb to 1.4v and the northbridge and one notch on the south
and vcore is at 1.4 bios for 1.36 idel in windows


cheers jimbo will try and have a play and get back yo you all cheers
