Can my 3500+ go any faster?

[keichan82]

Hi all. I oc my 3500+ to about 2500mhz with stock hsf. its currently about 58c. vcore is at 1.70v. im using 227mhz x 11. memory is at 1.80v. its timing is 2.5-3-3. my vcore CAN go to 1.75, but should i? will it be too hot?
any suggestions will be helpful. thank you.

You are getting on the edge of too hot.. don't go any farther without investing in better cooling. Thermaltake, Zalman, something like that will cool you down 5-10 degrees, and should let you push it to 2.6k.

I'd be happy with what you have for now, especially with the stock HSF.

i actually change the multipier last night to 10.5 and up the clock mem to 238mhz. now its running @ about 2511mhz. will that be faster in terms of fsb and ram? or is the 11 x 227mhz better?

 

[keichan82]

sorry for double post

by doing so, i was able to drop my vcore form 1.7v to 1.65v. it dropped my cpu temp from 60c to 53c.

You seem to have a pretty good chip, I would get a new cooler if I were you because those temps are a bit high although acceptable.

 

[keichan82]

i was thinking about getting water cooling.. but if my limit is 1.75v and i'm already at 1.65v will cooling still make a big difference on my 3500+'s limit. its not stable on anything above 240mhz even when i raised my vcore oto 1.7v... my temp was 66c with 1.7v vcore running prime. will cooling make it more stable? or do i have to increase the vcore some more to make it stable at 240mhz and above?

generally, a higher FSB and a lower multiplier is better at the same clock speed than a high multiplier and a low fsb. the question is can your ram (and your chipset) handle the higher fsb. seems to me that you may be having a problem with either your ram or your chipset if you can't get it over 240mhz. you did say 240mhz right? I would assume that that is your fsb? you should be more specific...is that your ram clock or your fsb? also your temps are hot. watercooling will make your system cooler but i'm not sure if it will make it OC much further.

 

[keichan82]

my ram are fine, its the fsb that won't go any higher. if i push it anything higher than 238mhz, then it wont even last 1 min with prime.

 

[MDme]

how would you know your ram is fine? try to use a ram divider and see if you can get a higher fsb with a lower ram clock. that way you'll know if it's the ram or the fsb.

OCZ PC4000 won't do more than 238? I don't think so...

could be the mobo, as he said the RAM is fine.

 

[MDme]

that's what i said. use a ram divider to get the fsb up while keeping the ram below 238. that way if it STILL crashes after using a ram divider and a higher FSB then its the mobo.

 

[keichan82]

i figured that the ocz pc4000 ddr500 would run perfectly fine up to 250mhz fsb without any oc. i hope that this is true, thats why i bought it. if not, how can i test it?

 

[keichan82]

where can i get the ram divider?
also, could it be my power supply?
im using aspire 500w and the +12v is @ 11.1 .... i have my ocz powerstream 520w but did not install it yet.. could that be the problem?

 

[MDme]

if you want to test your RAM at 250mhz then you can set the multiplier to 8 and use 250 FSB with 1:1 ram timing making your RAM run at 250mhz. that will only give you 2.0ghz and SHOULD run if your RAM AND MOBO would support it. this will eliminate the CPU from the equation.

If it won't run use a 166:200 ram divider and set your FSB (not RAM) to 250 and run at 8 multiplier. Your ram will run at 200Mhz and your CPU at 2000ghz with a 1:10 ratio. IF it runs then your problem is the RAM. if it does not run then your problem is the MOBO.

Hope that settles it for you. make sure your vdimm is at 2.8v and your CPU has adequate voltage.

 

[MDme]

the aspire PSU is crap. i thought you were using the OCZ already as it is in your sig. use the OCZ but do what i told you. so you will know which is holding you back.

 

[MDme]

sorry for the triple post....look for something like ram clock or max ram clock...it is usually set to auto, or has values like 200, 166, 133, 100 etc...set it at 166 to test between your ram and your mobo

 

[keichan82]

thanks. im going to install the ocz psu and test it out tomorrow.
(studying for midterm rite now)
ill post the results tomorrow to see if theres anymore advice.

 

[keichan82]

just installed my ocz 520w powerstream. tested my comp as asked above. booted @ 8 x 250mhz.. but did not pass the prime test. is there something worng?
i tried to reduce my fsb multiplier (i think thats what its called) from a 5 to 4. it booted at 230mhz x 11 but did not past the prime test.
any other suggestions?

Didn't read entire thread......did you lower the HTT?
