yeah try it on blend.. small fft will drive up the cpu temps but doesn't do memory.. if you can pass blend and work your way up gl.. sounds like alot of fun =]
The CPU at 4Ghz is completely stable if i just test the CPU, so it must be something to do with the RAM.
try looser ram settings and play with the voltage.. your there if you have it at 4- just have to get the right timings/voltage for the speed it's running at.. I like low speed tight timings at 1:1- usually find it gives equal if not better performance than high speed loose timing
Im a Complete Noob at this, what would be a Looser Setting? Stress Test is nearing an Hour at Stock CPU Speeds, but the Memory is at 400Mhz not 508. so gonna go back into the BIOS....
Right, got this to happen Strange thing is Orthos and W7 Say my CPU Speed is 4200Mhz, but i know its 400x10 and CPU-Z Shows This. Only thing is, the RAM is now running at 800Mhz, not 1066, Dunno how to make the RAM Run faster, and if i would see a performance increase anyway. Was just Running FurMark to see what temps i Would get at Full Load.
thats perfect, I'd keep that fsb at 1600.. 1:1 at 800- what I mean by tighter timing is.. try 4-4-4-15 on the memory and see if she stays stable.. you can keep playing with this for the tightest ram timings at 800 instead of trying to run @ 1066 and looser 5-5-5-18.. keep the 2T command rate too.. you can usually get away with 1T at around 750 and under only if you type winsat mem into the cmd console (run as administrator) you can get an idea of what your memory copy speed is like with different settings.. alot of newbies think.. oh it's running faster speed therefore it must be faster- but if you look at the looser timings, it negates the performance you just gained alot of the times using tighter timing, lower speed.. winsat will give you a good idea of your actual performance have to say gj =] pretty good oc for a new guy
So, would i just change the First 3 Numbers? Or Would i go 4-4-4-15, then if thats stable, try 4-4-4-14? Thanks, the E7400 is pretty easy to Clock, 4.2Ghz is in there somewhere, but it cant be heat stopping it, just fails Orthos.
It is not just CPU heat that will limit your overclock, the northbridge and other parts of the motherboard will also heat up and limit the OC. If you change the Ram to 4-4-4-15, you would actually be tightening the timing, you need to increase the timings to loosen the setting, i.e. (6-6-6-18), do not that use that figure, I just made it up to illustrate a looser timing.
Ok, im still trying to reproduce stable results, like the ones i posted, something must have changed.
it's the voltage.. I assume your on auto voltages- you should manually set all voltages your letting the bios decide and that could change with each oc.. if everything is set manually, you can reproduce it every time.. keep a log of the settings that work, you can fall back to those as you move up in speeds
Nope, the Voltage is set to 2.2, higher than what the RAM says, but 2.1 didnt agree at all. And i save settings to the OC Profile if they are stable, i have one set basically default, and one set at my last stable settings.
I think he's talking about CPU voltage, not RAM voltage. NEVER overclock with auto settings, you need to manually set your vCore.
Of Course i have controlled my CPU Voltage! Thing would probably be fried. Its set at 1.32, it was stable at 1.3, but unstable at 1.29, so i bumped it up a little.
Sorry, I skim read the thread but couldn't see that you'd manually set the Vcore anywhere. In any case, auto voltages wouldn't fry the CPU, it would just cause instabilities like you've been experiencing, which is why I thought that's where your problem lied.
Oh ok, i dont think i mentioned it, but it can be seen in the Screenies. Havent done any testing tonight, as im not sure what else to try....
This is my mem settings,Corsair 8500C5D spd disabled 5-5-5-15-6 write recovery-42 trfc, volts 2.0, 1:1, 450=900mhz. have you disabled C1E, speed step, spread spectrum. have you set Pci express frequency to 100.
Ok, most of the Stuff is set to Auto, so i will go and have another look, be handy having a Laptop now What should the Chipset Voltages be?
go stock and read what they are set at on auto.. use that as a baseline- go up from there.. ideally you want the least amount of voltage you can get away with.. why I was saying keep a log of what works and move up from there
