Windows 7: Finally worked out good overclock!!

26 May 2011   #11

Windows 7 64 bit
Better more stable overclock

Been playing around once more and this seems the most satisfactory setup on my system, increased my pass test 64 score by 120 anyway, not bad at all.

FSB is now at 240mhz
Dram at 400mhz, 6-5-5-5-18-20 1T
HT link at 1920mhz

Processor is now at 3360mhz or 3.36Ghz 20% overclock

My RAM really is at the limit now with these tighter timings, I just cant push it anymore, i tried to eek it out to 405mhz and i got a BSOD when running stressful software, I would prefer my HT link to be closer to the 2000 mark but the system is faster with the RAM and the Processor Higher with the HT reduced, The other option i have for the HT would take it to around 2120 sticking with the same RAM and CPU settings but this causes instability.

This is very stable and actually gives me better temperatures than running the HT higher, my CPU at full stress is 62 C now, this is reduced from the 66C as shown in the last attachments. hoorah

That sounds like a good 24x7 overclock as long as it is stable. Have you stressed IBT or Prime95?

Hi, thanks for your interest, i downloaded Prime 95 but couldnt get on with the software, i think it was because it wasnt really designed for testing cpu's, i understand that it does a very good job of it, but didnt like the idea of utilising my system for over a day without being able to use it, lol!

Tried OCCT as well and i found that to be more user friendly as were.

I think the last overclock maybe put too much strain on my memory again, not sure got a BSOD while playing FSX, said that a secondary processor had missed some data or something, maybe you guys could explain that one better to me, anyway, did more resarch, and have eased the FSB to 238, 14x multiplier, SPD DRAM running at 395.8 with the HT running at 2137.

This gives me 3325Mhz or 3.32Ghz

I just wanted to ease back on the DRAM side, although to my mind the secondary processor would be the NB???? Not sure.

Cause i have eased back on the DRAM i dint want my HT to go down even more so i put it back up to the next setting in my BIOS. My BIOS doesnt really allow for precise control, when HT and DRAM are set to manual, it applies a multiplier and gives you the options available for each, so the 2137 is the 2nd highest option with 1906 being the third.

I know I am being limited a little by my RAM but its very standard RAM and obviously its not the faster 1066Mhz which would allow more freedom.

I set off wanting to get 3.2Ghz out of it, that was fairly easy my ambition now is 3.35Ghz and i am nearly there if this one works.

Hoping the extra voltage will just help ease this one along....

I have raised the CPU voltage by one increment or 0.0125V and also the NB voltage by 0.0125V, seems to be perfoming ok, so far! FSX crashed again last night but no BSOD, FSX seems to crash alot anyway, been using everything else ok, have a lot of freeware in FSX so anything could be tripping that out!!

Don't overclock then.
Also, talk about a run-on sentence...

Sorry you don't like the English language.

The reason I say that about my PC is cause I do use it every day, hence my quest for stability in this.

Just doing some video encoding to h.264 and this stresses the CPU at 100% nearly all the time too, its one of the highest CPU demand jobs you can do, again why I want to maximize my system, surely this practical application on the CPU demonstrates reliability.

I can report that its doing this task well with no problems. 63C max CPU at full load constant. My mcp is at 50C stable.

This does indeed seem stable. although with my ram reduced by 8Mhz and my Ht increased from 1920 to 2137 Mhz, my passtest score reduced by 70, so i am only up 50 on my origional overclock.

I did read somewhere that graphics are not helped by having a higher HT clock.

Wondering whether the lower HT figure of around 1906 will actually give me better reults??

Here are the stats for this final overclock, I really cant go any further as my RAM doesnt want to know, without changing the timings at any rate, dont want to do that cause the timings are quite fast at the moment.

HT Link better higher AMD 630 II X4 overclock

Well, I have continued to make progress with understanding the process of overclocking this CPU.

This is by far the best setup that i have achieved still limited of course by my RAM, with 1066 RAM, i am sure that more is of course possible.

FSB : 244 Mhz
Speed : 3.412 Ghz
DRAM : 406 Mhz @ 6-5-5-3(5)-18-20-1T (3:5 ratio)
NB : 2437 Mhz
HT Link : 2437 Mhz

CPU voltage raised to 1.45V
CPU/NB voltage raised to 1.175

All other voltages on AUTO.

This is very stable and whats more it is quick, i have noticed a boost in application open times, virus scans, etc, with these settings the performance increase i was expecting are being achieved in the real world not just theoretical.

The chip seems to like the HT link being the same as the NB which is understandable.

My board supports 2600 HT link which is effectively doubles, so the 2437 really isnt an issue, some sites have suggested that keeping this near 2000 is better, real world difference is in keeping this locked with the NB frequency.

The RAM is being very marginally overclocked and the BIOS is giving the RAM 1.9V which is 0.1V over stock, but to keep the tighter timings this is probably neccessary.

The PCI-e bandwidth apparently runs at 2500Mhz so the 2437Mhz HT link which feeds into the PCI-e system via the southbridge is approaching the same level which should make for a streamlined performance, ideally i feel that the processor would hit a sweet spot at 250 Mhz FSB but my RAM is being stretched quite a bit then.

At 250 Mhz FSB the processor would be giving 3.5 GHz, which is nice.

Am gonna add extra CPU cooling in the form of an artic freezer fan with heatsink and heatpipes just to ensure the CPU stays cool at these new settings.

So there you go, I am sticking with this as the computer is quick now, multitasks really well and I am satisfied that the performance is better in real world terms.

Enjoy your AMD especially the new X6, which is making me kinda jealous!

Played some more and have got a very stable system at:

FSB: 248 3345Mhz or 3.45Ghz Vcore at 1.46V (1.475) in BIOS
DRAM: 411 running at 820Mhz 6-6-6-6-18-24
HT: 1975Mhz (again i read that 2000 is best, thats the processor limit, not the board)
NB: 2480Mhz at 1.175V in bios

Also just installed a new GTX 470 Graphics card, small overcloc on that at 797 mhz processor and 1740 Ram at 80% fan, just for gaming of course.

Idle temps on my CPU are 49C Load temps are 63-64C fully loaded for over 30 mins.

My GPU runs at around 82C with these settings, not high for this card apparently!

So thats my new spec updated accordingly.

Moving on up!

This overclocking lark does become addictive..
Ok so i have this Athlon II X4 630 2.8Ghz Chip, not a bad chip but not a great chip, hehe.

It does seem good value however when it is now running stable at 3.54Ghz!

Here are the figures....

FSB = 256 @ 1.500V
Multi = 14 x (locked)
NB = 2560 @ 1.275V
HT = 2048 @ 1.300V
DRAM = 424 @ 2.000V 6-5-5-15-20

I know this is not the highest, but for my first serious overclock, i think it has been fruitful, the chip really is not for budging now though, have tried allsorts, the DRAM is limiting me again i feel, managed to eek just a little more out of it, have also recently installed a 4th ram stick, something that has never been achieved on this board before, it would always have nothing to do with it on certain ram slot, anyway jiggered about with the ram trying different configurations and the slot came back to life.
So now running 10GB on this system, 1 x 4 and 3 x 2, its quite happy with that suprisingly.

So after upgrading my case, my graphics and my ram, i have now ordered an AMD Phenom II X4 955 BE to play with, this should complete the overhaul of my system.

I plan on trying to get that up to approximately 3.8 - 4.0 Ghz but it was the L3 cache, and the unlocked multiplier that sold it to me, as i can maximise the ram without having to push it hard by changing the multi rather than the FSB.

Probably more to follow when i obtain the said chip!
