ibenq vista 32 bit can fully utilise 8gb ram?

nope... installed for fun ... now got 2gb nia ler... didnt update siggy @@

oh ok, i thought vista 32 bit can lol

32 bit can detect 3GB the most..

i know 32bit can support up to 3gb, i thought vista have patch to fix it .....

Q8200 is faster than Q6600 clock for clock, runs cooler and consumes less power. If your target is only 3.2Ghz, I'd go with Q8200. Math shows that you only need FSB of 457, which isn't all that difficult.

To get your RAM to DDR2-914, which is what you need for FSB457, give it more voltage (around 2.1 to 2.2 should be ok) and loosen the timings a bit. Run memtest to verify.

But for sure it will have trouble hitting 4.2ghz air/liquid 3dm06 benchable and 3.8-4ghz 24/7

Haha that's a motherboard issue, not core issue =p 4.2Ghz is 600x7, even 3.8 is 543x7..what's the limit for UD3P?

Quad Core 24/7 stability usually drop off at 480FSB,with 510FSB or so max on some good quad core clocker so that is 3.57ghz is more or less 24/7 limite
So far,haven't see 600FSB yet
Max i saw and that is good,580FSB validated
So,max validated with ideal condition and all,come to around slightly over 4ghz or so but not stable for multi core benching for sure

Thanks guys... I appreciate all the input, I definitately learnt a lot.

Since i'm a noob at OC... I have absolutely no idea what's the FSB thingie but from your explaination... I'm guessing you're saying Q8200 using normal Kingston RAM and the EP45-UD3L motherboard can do it without a problem?

Can give more details on what should I do to get my FSB to 457? Sorry... I know I should do more reading b4 asking so many questions *blush* ... but I have to decide tonite bcos I'm buying them tomorrow.

Thanks again!

32bit vista can detect my 8gb with no whatsoever patch, but only uses 3328mb of ram

just up ur bus speed to 457... and up voltage for ram,proc,northbridge if necessary

Ic ic..yupz kinda thought the limit was around 500FSB. I personally felt it with the Tpower+Q9450 last time, even 505FSB needed drastic voltage d.
Anyways, sorry to TS for taking this thread OT, just wanted to confirm the limits with OC4/3 =p

Sigh nvm, I'm free (and in a good mood) so I'll explain from scratch.
Intel C2Q processor speed is determined by FSB times multiplier. In a Q8200's case, that figure is 333Mhz(FSB) x 7(multiplier), which gives us 2.33Ghz. Since your multiplier is low, that would mean that to get to 3.2Ghz you require 457x7. (Intel FSB figures are quad pumped, i.e. FSB1333=333.33Mhz, DDR figures are double pumped, i.e. DDR2-800=400Mhz).

Another issue is your RAM. The lowest speed you can run your RAM at is 1:1 with your FSB speed. Thus you require DDR2-914@457FSB, overclocking your RAM by 57Mhz.

Next let's talk about Q6600. To get 3.2Ghz with Q6600 is really easy. Q6600 is 266x9. To get 3.2Ghz, you want 400x8 (you can set multiplier lower, but not higher than what Intel gives you). 400x8 is ridiculously easy since your RAM and board are running at spec.

However Q8200@3.2Ghz will be faster than Q6600@3.2Ghz I'd say by 8-10%. Also, Q8200 runs cooler and consumes less power.

Finally let's talk about practical limits. New Q6600s rarely get to 3.6Ghz, you're most likely to get to 3.2 or 3.4. Q8200@3.2Ghz will outperform it.

So in conclusion what I'm saying is not that UD3L+KVR can take Q8200 to 3.2Ghz without a problem, it will be able to do it, but with proper tweaking. That tweaking is IMO worth it, to get the 8-10% performance and the power and heat savings over Q6600.

Now to get your FSB to 457, take it slowly. Go to 400x7 without messing with Vcore. Set Vtt to 1.35V, Core GTL Ref 1 to 0.63x, run IBT 10 loops and test for stability. Then go up 5Mhz at a time, whenever you fail IBT increase Vcore or Vnb 1 notch.

Usually in game performance, the Q6600 is slightly faster than the Q8200 as seen in this review. This is usually due to Q6600 bigger cache and slightly higher clock speed.. As can be noticed, games loves cache (and clock speed).

Talking about overclocking, the Q6600 would be the easiest to reach 3.2GHz... using standard RAM and motherboards. Which is why Q6600 gets my vote in the beginning...

However for Q8200 to reach 3.2GHz, there are hidden/extra costs involved such as getting a better (expensive super overclocking) motherboard, performance RAM (going above 400MHz system bus means the RAM will have to run faster than 800MHz, that means DDR2-1066 RAM is recommended) and the best 3rd party HSF (heatsink and fan). Going above 450MHz system bus (or 1600MHz FSB) isn't easy..

how about QX6800 ? whats the OC FSB value if i want to take it to 3.2-3.5 Ghz? mind to explain to me as well coz im a new in OC too , Thank you very much >.<

im using the Biostar TP43 HP Mobo and a pair of value RAM of DDR2 800 Mhz.

actually i do not intend to adjust the CPU voltage as i heard that it will somehow shortened the life span of the processor. Any guides ?

QX6800 is already 2.9ghz at stock speed. so u didnt need to do much tweaking just to get to 3.2ghz.

bout that (voltage), yup. it will shorten the lifespan but only if u push it too hard. if just do light OC, there wont be much damage or maybe none. (note:decent cooling is a MUST if u're into OC)

Dude,just pop calculator up and calculate,easy

normal usage without OC, but use for 3D rendering, wat do you guys think? Q6600 or Q8200? or any better and cheaper proc? 3D rendering requires more cache or FSB? gaming requires cache or FSB?

Try:400x8,5:6 divider aka 480mhz/DDR 2 960,1.95vdimm and PL7 or so.
Vcore try yourself
