try ramming it down to 5-6-6-15, Rev C doesnt take 5-5-5-15 well

Hi.,bro I'm a newbie here.,i just want to ask.,can i change the multiplier for E6300 in bios..tq

yes u can, but only downwards..

I already only can OC my rig to 2.8ghz
= 400fsb.,but i cant reach 3.0ghz=420fsb.,is there any problem with my settings..

Upped ur Vcore? Vmch? which D9s are on ur crucials?

i dont have any idea which D9s on my crucials because it covered with the heatspreaders.,i just buy the crucials from shawty last wednesday..

Should be D9GMH. These rams can do nicely at 500FSB 1:1...effective clock 1000Mhz 4-4-4-8 at 2.3v

loosen ya timin 1st to 5-5-5-15 while u tryin to find ya max speed of ya chip. yas should be of d9gmh, which can do 1000~1200MHz @ 5-5-5-15 no sweat...

try to up vmch by a notch, it's a must for my case.

tq bro for the info.,ohh.,before i forget.,1st attempt on OC.,my CPU runs at 2.8ghz=400fsb.,but the temperature when running orthos up to 78C..the core temp and itat shows 78C but everest only shows 63-70C..which one is true..

Whether 70C or 78C....it's still very hot. Try resiting the heatsink or reapply the thermal paste. Btw, you are running on what vcore? Try not to exceed 1.5v with air cooling.

try to lower ya vcore bro, u pumped ~1.46v into ya chip? dats kinda high & not suitable for 24/7 imo... i folllow coretemp temp, however there some prefer speedfan or others...

Hi guys, wonder is 63-66c core temp ok i oc to 3.2g @1.306v, my hardware at my signature. TQ

yup it's perfectly fine

Tq bro.,BTw i didnt pump my vcore setting.,i run with default setting at v1.325.,i dont know why coretemp showing 1.46..

Just out of curiousity someone in the forum stated not more than 50c, is it true.

Nope, totally not true. LOL

Thanks bro..

Actually the VID voltage range is 0.8-1.5v, so I don't suppose 1.46v is that bad.

The problem is the heat and if we can get rid of the heat problem, bumping more Vcore is alright.

Currently with the stock cooler, I can't be bothered to o/c any further

Hey, guys. Kinda new with OC here. My idle temp for core is 49-51C and load went up to 70-71C at 3.2Ghz. Vcore 1.3. Is that normal? Using stock cooler here. Tnx.

Yup the problem is the heat... if you can settle the heat issue it should work within that range.

Should probably get a better cooler for it. 72c is max tcase for the E6750 and 71c is going to be very borderline.

If I invest on a Phase Change, it costs RM600 and IFX-14 + 2 fans would be around RM350

Cheaper solution is to get the Cooler Master GeminII

What are you going to use if you upgrade ? usually the best air coolers are never around until the socket has been in use for a while even if the best coolers came out immediately, you'd have to spend another Rm350 . If you use a phase change you can use it for years. I think in the long term you'll come out ahead. The GeminII's already obsolete, according to Xbitlabs it can't even cool a quad core enough for any decent OC-ing.

I'm not a good oc-er but just wanted to have a bit of fun I'm still considering what to get since I'm using the stock cooler now.

Get the Ultra 120 extreme or IFX-14 or Xigmatek S1283.

GeminII not a "great" heatsink but it is cheap though.

If not mistaken, u are using E2140, right?
Usually E2140 max out around 400fsb, so any cooler that within ur budget can go till 3.2ghz will do.

I need something great to help me reach 3.6ghz on my E2160

Actually I'm running 5:6 divider so the FSB is at 475Mhz now. I haven't tried going more than 400FSB 1:1 and the max was 3.2Ghz

yeah agreed, gemin might not be the top 5. but let's see from a wider perspective, it cools the NB, PWM, and RAM, with a compromising a little on the cpu load temps. Can the xigma, and tower like hsf cools the rest?

So 5:6 means your RAM is at.. 570 MHz ?

Emm, it's 475 only:

It should be better if can get 1:1 400MHz /4-4-4-12..

Hi, is system temperature 46c acceptable with oc at 3.25g@ 1.306v vcore n my v dim at 1.9v ram ratio 1:1, core temp at 63-66c but my mobo detect temp at 46-47c, my spec at my signature. TQ

You can check at http://processorfinder.intel.com/ -- just look at the Thermal Specification. The load temp (with orthos running) should be about 10c below that.

§layerXT, higher FSB should be more beneficial than lower FSB with tighter timings. This can also be seen if we run benchmarks. Of course, I'd like to run 480 1:1 if possible

Well TTR says higher FSBs may not be better than tighter timings. From http://www.thetechrepository.com/showthread.php?t=195 you can see that they make an interesting case for tighter timings as opposed to higher frequencies.

So what board and RAM are you using ? mine doesn't have a RAM multiplier under 2X

Bro, u are trying to tell me which thermal should be 10c down

wodenus, in fact timings would play a role too but in this scenario, it's a difference of 75Mhz between 400FSB (1:1) VS 475FSB (5:6).

In terms of timings, 400FSB 1:1 might be tighter (14-4-4-4) compared to 474FSB 5:6 (15-6-6-5) but is it enough to compensate the gain from the 75Mhz FSB increase?

I'm not sure but running memory benchmark shows that FSB at a higher frequency (in this case 475Mhz) shows better numbers eventhough the timings are more relaxed. Opinions anyone?

Do you mean speed benchmarks or latency benchmarks ?

Memory Bandwidth Benchmark, not the latency one. Shall I conclude Latency should be placed first then only bandwidth?

I use the formula from http://www.thetechrepository.com/showthread.php?t=195 -- but then I only use 1:1 so for me it's just a matter of how much i can optimize the timings after I hit the FSB wall. I use the formula from the post :


Latency (ns) = (CAS*2000)/Effective Freq in MHz

So at 400 FSB CAS 4, latency is (4*2000)/800 = 10 ns

At 474 FSB CAS 5, latency is (5*2000)/948 = 10.5 ns

So you can see here that according the this formula, 400 FSB at CAS 4 is very slightly faster than 474 FSB at CAS 5.

Cool stuff wodenus, thanks
Btw, how about the FSB gain? In terms of 75Mhz increase, are there any formula to see how much benefit?

Yea if I can do 410 4-4-4-12 on my cheap value RAM, he should be able to do a lot better.

61C CPU temp when 100% load. Core temp around 71C. Is it normal for E6750 using stock cooler at 3.2Ghz?

thats a bit on d high side. u might wanna change ur cooler to an aftermarket one..

I think that's basically the load temp with stock coolers. I'm having that sort of load temp myself

E6300 only have 2 multiplier, 6x and 7x.

What software are you using to check the core temperature? And what app do you use to load the CPU 100%.

71'C is a bit too high. What's your vcore? The E6750 can go 3.2Ghz at stock vcore....

Stock Vcore. Using Everest Ultimate to check core temp and Orthos on 100% load.

I see. I'm don't have Everest Ultimate. Try using core temp version 0.95.4. It is supposed to be a good app for monitoring the E6x50's core temps.

Anyway, it is generally not advisable to run your CPU 24/7 at more than 60-65'c....

Bro, mine running at 63-65 now from 67-70 becos i change the heatsink fan, temperature detect from core temps. is it advisiable to run at that temp, becos this is the best i can reduce the core temp. TQ

You're using the app "Core Temp version 0.95.4"? If so, then 63-65'c is ok although a bit lower would be better.

Again, these temperature cut-off is very subjective. Some people run then procs at 70'c without any short term problems.....
