Which Intel CPU

[Terbinator]

Them Biostar motherboards seem to be the dogs when it comes to overclocking.

You can get a high VID E7400 to 4Ghz easily enough as well, it just takes a little more voltage. Easily doable without going nuts though, even the E5200 can do it. The only dual core CPUs you can't take to 4Ghz are probably the older 65nm ones.

4Ghz are probably the older 65nm ones.

Ive hit 4 on my Q6600 and the ol C2D X6800 have reached/beat 4Ghz.

[sammorris]

Only one specific batch of Q6600s (L7 something) could get to 4Ghz, and it took at least 1.55V. Taking reasonable voltages as being +200mV from the VID, it isn't really possible with 65nm apart from the extreme or ex-extreme ones (X6800/E6850 and QX6850)

I was sticking around 1.5 in mine and it was idling at 50c on a FP7 at full fan speed lmao, also it doesnt matter it was still doable How long do you reckon that 8Ghz (prescott?) has left?

45nm can pass 4GHz easy, but the temp sensors are shocking.

My E8600 showed like 5c higher than it actually was.
My Q9550 shows Core3 as never going less than 41c, but it can go higher...

65nm sensors are alot better.

Personally, i'd always get a 45nm quad over the 65nm ones. However, the Q6700 does look tasty with that x10 multi.

Id take a 45nm also but at the time i bought the Q6600 the Q9550 were £260 in comparison to £140 for the Q6600 so it was a no brainer for me.

3 GHz should be easy (with my non existent experience of overclocking intels)

[sammorris]

Yeah the coretemp sensors for the 45nm chips are shocking, that's why I always use the main CPU temperature instead.

I'd like to thank CAT-THE-FIFTH and others in this thread, am going to go with the Q9550 and the Shuttle SX48P2E Barebone ( DDR II ) model and save me some cash

Should have the new build sorted for nextweek all being well.

Question, see has i have saved over a £100 would it be better to upgrade the gfx at this time and if so what would you go with, a 4870, 4890 or other ?

[Terbinator]

Both are great cards but personally i would go for a 4890 at current prices!!!

I would also make that assesment.

I would save the money and see what ATI DX11 cards are being released next month. It is better to put money towards one of them TBH. Your HD4850 especially with some overclocking will do the job fine. Remember the HD4890 is basically a highly overclocked HD4850 itself(with a slightly different core so it can clock higher) with GDDR5 RAM. You don't want to be kicking yourself if the next ATI generation is much better than the current.

Fair enough, I'll hang fire, might use the money to get 8gb of ram instead , but this does mean i'd have to look at moving to 64bit O/S....

Your chips are all 64bit, so having an O/S to match makes a lot of sense, particularly for the future when you'll need more than 3Gb RAM

I would check the Sudhian forums and even post a question about RAM for the X48 based Shuttles there and whether they are stable with 8gb- unless you want to go on multiple RAM adventures!
