hi i've recently built a new pc its under 2 weeks old and im having troubles overclocking

ok ive bin readin bout ppl makin der q8200 get to 3.0ghz easy when i try (first with mem unlinked and at 1333) i can only get fsb up to 1470 which has bus of 367 and clock of 2.57ghz any higher it will boot but after i log in and the desktop shows within 10 sec it eaither freezes or gets BSOD. wat shud i do?
i then tried upping the ram since i hear tht with ddr3 u need to up it (i supose tht its on a x3 multiplier or sumtin like ddr2 is on x2?) but even so at 1333 mhz i shudnt have to up ram til i get a bus of 444. this didnt help.(i had also bin playin with my voltages a bit to much raisin sum of em at leats .2v)
this didnt help. i then reset and trind with linked ram i could not get any futher (this was without volt changes tried with but didnt help and other ppl did with out)

my voltage changings have mad me puzzled there defaults are (1.2vcore,1.1fsb,1.5dimm,1.3spp(orsumtin),1.5mch) ive tried rasing these to (1.3,1.2,1.5,1.3,1.6) and even futher on a 1600fsb.ive gone high enough to get beep of death wat am i doin wrong?
and which fsb-ram linked setting shud i have it one (sync 5:4 or 3:2) or shud i just put it on unlinked (in which case wat is a reccomended ram settin)


im stuck here i know its not cooling my cpu runs max 40c idle(just on core 0) the rest about 32c
plz help ty

Hiya, tht13! Welcome to OCN! You came to the right place, so let's get started on overclocking this. I'll try my best to answer the questions, and I hope that it will at least get the ball rolling in the right direction!
Believe it or not, DDR, DDR2 and DDR3 are all multiplied by 2. "DDR" means "Double Data Rate". But DDR2 and DDR3 are advancements in DDR technology. I know that it's hard to believe that DDR3 should be the "best" based on this experience so far, but we'll smooth everything out. It should eventually end up being like butter.
Based on this, I recommend trying the vcore at 1.4V (in the BIOS, but it'll actually be less, which you'll see in CPU-Z), then trying the FSB at 1.3 or 1.4V, and perhaps 1.45V SPP (north bridge) and the rest can be left alone for now. But the 1.6V might be a little high, so I think it should be brought back down to 1.5V - but I'm not entirely sure yet. I'll have to think about it. But 1.6V for it sounds a tiny bit high - but not like too high. Just more than what might be necessary (I think).
I personally recommend using Unlinked because it made overclocking a much easier task for me. When using Unlinked, you have to manually set the memory to stock settings. This includes the clock, voltage, and timings. These values are usually found printed on a sticker that's on your memory sticks. They're sometimes also found in the Timings Table in CPU-Z's SPD tab. Here's an example of that:



That's my memory. My personal recommendation is that if you have multiple columns to choose from, then manually enter the values in the far-right column in your copy of CPU-Z. This includes using the voltage as well.

It's best to start with the memory at stock according to what the manufacturer's SPD information is so that you can overclock the CPU first. This way you're not changing a large amount of variables, and it'll be much easier to diagnose any problems encountered.

But when you're done with the CPU and then ready to tweak the memory, it's best to leave the memory clock at stock and get the tightest timings that you possibly can. This includes changing that Command Rate from 2T to 1T. It may not be possible to successfully achieve 1T, but if it is, then it will require a little voltage increase, and it should also require that you loosen the CAS# Latency by 1 or 2 at the most. But usually, just 1. So, I had to change that 4.0 to 5.0 (although, I don't say "5.0", I say "5").

You see, the performance difference in the way your system feels going from 2T to 1T is noticeable. But leaving it at 2T and just overclocking the crap out of the clock won't make things feel much different at all. But not only that, you'll also see a bigger boost in performance in benchmarks as compared to just raising the clock speed. This is all because you have the nForce chipset. If you had an Intel chipset, then I'd be recommending that you raise the clocks and then tighten the timings down on top of whatever overclock you get. They're fairly different chipsets that way.
Oh, that's just a stuck sensor, and it's nothing to worry about. Besides, all that really matters is what the full-load temperatures are. Once the temps exceed approximately 40°C, you will notice the sensor begin moving.

I have much, much more information regarding temperatures, temperature monitoring and other things. It's all contained in a thread posted by our very own ChickenInferno:

TJ Max and Temperature Monitoring Programs

Read through the OP of that thread and as many replies as you can, especially the ones by ChickenInferno. Once you finish reading this, you will be able to totally relax. It's fairly complete information and education, and it's all necessary. So read it now, because you'll eventually have to read it anyway in some shape or form.

Anyway, one final note: for monitoring temps, make sure to try Real Temp. It's probably the best temperature monitoring software there is thanks to it's really well thought-out GUI. And when stress testing, be sure to select the Small FFTs test in Prime95. I mean, the default test is the Blend test, and that's not going to properly stress test the CPU. The Blend is used later. But, it's the default selection because Prime95 wasn't designed to be a stress testing program. It's for something entirely different.

Anyway, I'll provide more information as we go. Before you know it, you're gonna have that thing overclocked and practically 100% stable. And it's all thanks to your decision to come to Overclock.net.

hi
i tried your advice with the voltages (1.4(actual 1.36),1.3and1.4, 1.7(default ram setting as recommended in unlinked)1.45,1.5) i then put the ram on unlinked set it to 133mhz and put the timmings on stock(9-9-9-24) and then the fsb on 1550 as opposed to 1470. this ended up as usual in bsod or computer freeze at the desktop.
i then tried a fsb of 1500 mhz, this resulted in bsod, and finally i tried 1475(just 5mhz over wat i can acheive) and this then resulted in bsod again(rly sick of dis now)
im now gonna go back to my original overclock with your recommended ram settings, and im also trying T1 settings on ram (this bit actually worked)(now gonna check if i get a highed 3dmark.
wat do i do next?

quick update
tried changing voltages but kept on giving be bleep of death on any setting besides default(its stopped doin this now) and then sumhow managed to get it on 1500fsb with default volt. tried 1550 with defualt and volt up 10 vcore 1.4 and fsb 1.3 but got bsod
now with these volt i tried to find the highest i cud raise the fsb
the highest i cud get on those voltages was a 1510 fsb cpu speed 2642,5mhz
i then tried to lower voltages as much as possible to still boot stably

however the voltages didnt reduce much so i decided to put the fsb back to 1500 and voltages on default

wat shud i do now??

I must be slipping or somethin because I'm feeling stumped. I'm sorry, but I keep coming back to see if I have a "eureka" moment, but I haven't yet. I don't know what's going on with me.

ok
but i think there is a prob with my mobo or sumtin since ive raised my voltages up to the point where i get the bleep of death and ive only got it up to 1500fsb(for sum reason it decided to jump up to tht from 1470) but any advice is well accepted

Hmm. Well, try to avoid using Auto for voltages - that is, if that's what you meant by setting them back to default.

I say that you can try a 1.4V FSB voltage and see what happens. I've been told a few different times that these nForce chipsets really like to eat up FSB voltage.

no wat i mean by defaults is wat they r set on after a cmos reset which is sumtin like 1.2,1.1,1.7,1.4,1.5
ive tried a 1.4 fsb but it doesnt help much and any higher gives me da bleep

So the voltages are back on Auto. Auto is bad for overclocking as the BIOS can actually use more voltage than is necessary thereby producing more heat than it otherwise has to. And too much heat can lead to instability.

But if the voltages are at 1.2, 1.4, 1.7, 1.4, 1.5, then try something like 1.35, 1.4, 1.7 (or whatever your memory is rated for), 1.45, 1.5. But manual, not Auto.

If this doesn't help, then I don't know what else to do as I am a bit limited in knowledge. But it's beginning to look like I'm the only one who's got the time to post replies on OCN right now. hehe
