Make sure you have sufficient cooling on your board to handle the new voltage changes.

Good luck
Thinker, i cudnt find any voltage settings on ma mobo for the chipset Regarding voltage plz c ma previous post (hav edited that). And iam confused bout '300HTT' in ur reply abov Actly did u mean 2 say 300 cpu fsb????? . Coz in ma mobo i can only multiply the CPU FSB with HTT (i.e for eg: 278x1 or x2 or x3 or x4 or x5 or Auto) to get a certain value in Mhz.
ya i hav tried to push the fsb to 280.., but failed after benchmarking[Torture Test] for 3 hours & 30mints . Even i hav tried the same test after pushing both Cpu core & DDR voltage, but even then there was no use at al.
.
.
.
So thinker., plz think nd gimme suggestion if u hav got some..

JamY, to adjust the cpu voltage (Vcore), go to Advanced -> JumperFree Configuration. Look for "CPU Voltage". The HTT (reference clock or FSB) can also be adjust in that menu. Check "CPU Frequency".

Have you had a chance to read over any of the guides I posted above? When you have time check them out, it should shed some light on a fe wof your questions

Good luck

think3r, i got realy confused when u wrote "chipset voltage" in ur previous post. Actly u meant 2 say was "CPU CORE" voltage i guess. Well, I hav even tried by pushing it from 1.4v to 1.5v. But it cudnt come up

yes, hav gone thru all those helpful sites, but i cudn't find a new trick 2increase ma FSB inorder 2 get a Stable results

Down here it goes Ma Oc'ed Rig Details :-


And thankx 4 ur reply..

Jamy, just by judging by that screenshot you may have to adjust a few things. Try getting your HT (hypertransport) speed below 1000mhz. Right now your at 1114mhz which may cause some problems if you keep raising your HTT (reference clock). Change the HT multiplier from 4x to 3x.
Relax your CAS (memory sub-timing) from 2.5 to 3 and see if that helps. I would also drop your memory to a lower divider. Try and get that memory below the factory 200Mhz. I'd advice tweaking your memory later on after you've gotten your processor stable.

Try those things above and see if it helps

Good luck

think3r.., i hav done as u told. But y the HTT should b kept < 1000 Mhz. wat mi8 b the techinal reason 4 that..??? i wish if i cud noe that .

by the way i will juz add here the deatils f ma DRAM config :-

memclock index value : (333Mhz) [Shud i keep it in 333 itself..?? or reduce it ?? The minimum is 200mhz]

RAS : 8T
RAS to CAS : 3T
Row Precharge time : 3T
Row cycle time :11T [I shud change the timing here?? ]
Row Refresh Cycle Time : 14T [I shud change the timing here?? ]
Read to Write Time : 5T
Write Recovery time : 3T
1T/2T mem... : 1T [default was 2T. Shud i change it 2 Default...?? ]

Now here goes ma "Jumperfree config" :-

CPU Freq : 278.0
PCI Express Clk : 100Mhz [No idea watz this bout . Plz help ]
DDR Voltage : 2.9V
CPU Multiplier : x9
CPU Voltage : 1.425 [ Default was 1.420]
PCI Clk Synch Mode : 33.33Mhz [Am i right here?? ]

==============================================

Hav Reduced HTT below 1000Mhz. Now itz 835.5 [278x3=835]

So Think3r,,,, NOW WHAT????????????????

Sorry 4 killing ur Time.
And Thankz Again

JamY, your not killing my time I'm here to help

Let's clear up a few things. HTT is the reference clock ie 270mhz. HT is the hypertransport speed which at the moment is at 835Mhz. Just thought I'd mentioned that so you don't get confused.

Socket 939 typically likes lower HT speeds preferably below 1000mhz. Anything higher then that and you may run into stability issues. In some rare cases I have seen S939 boards hit 1000-1200mhz but it's not common.

Can you post some CPU-Z screenshots of your current overclock? Include each tab if you can.

At the moment don't worry about the PCI Express Clock. Raising it between 107-112mhz can yield some positive results with overclocking but not always. I'd also recommend dropping your VDimm (voltage for your memory) to 2.6volts. If your memory is not overclocked then kept the voltage close to factory (JEDEC standard is 2.5volts).

Let us know

Good luck

cool n quit - disabled (enabled) You mean tis is enabled? If so dissable it as it can also lead to unstable overclocks.

Go into the bio's and disable it..If it aint already.
I have a Venice core,I only used for about 2 weeks and is still boxed ext and that run smoothly at 2400MHz.It was the memory holding me back .other wise it would've gone further i reakon.

Think3r.., hav droped down the VDIMM voltage to 2.6v. ok thankz 4 the info but wat wud "HTT" stand for??? Is it so called HyperTransportThreading???? Plz correct me if am wrong..

And wat bout the "Memclock index value" & "PCI Clk Synch.. Mode"???. Shud i drop it too..???

k i hav added som f the previews f cpu-z below:-



now whattt???????? juz curious...

JamY, HTT is the "reference clock speed" OR FSB (you might be more familiar with that one). HT is "hypertransport" ie. the 835.6mhz speed listed in your CPU-Z screenshots. The second guide I posted discusses this. The "Memclock index value" I believe is your memory divider. Change it from 400mhz to 333mhz. That should bring your Memory frequency down a bit and allow for more overclocking room with your processor. Right now your 27mhz overclocked. When raising your reference clock the memory frequency will also go up which in some cases can cause instability. I'd also advice changing your command rate from 1T to 2T for now.
Have you had a chance to find each components(motherboard, memory, cpu) maximum safe limit? This should give you a nice baseline to start off with. This procedure should be in the first link I posted as well.

Let us know

Good luck

think3r, my memclock index value was already set to 333Mhz. Ma question is "Shud i reduce it again 2 maintain the cpu:fsb ratio ..??? "
Also wer can i find this damn ratio..????
Is it posible 2 maintian xactly 1:1 ratio on ma mobo..????????????????????????????????????
Also lemme try the link u hav posted. May b i can get more info from that ..
