CPU / GPU upgrade and OC...

jimbobaggies · 13 Nov 2010 at 11:01

Current rig;

E2160 @ 3GHz
Corsair HX520
Asus PK5C
4 x 1GB OCZ XTC Platinum Revision 2 - DDR2-800
XFX 8800GT Alpha Dog

Current games played are BF:BC2, CoD black ops, TF2, all the usuall fps really.

Can't really afford full on upgrade for some time, so thinking, something like Q8300 and HD5770 or GTX460 - spending around 200-250.

How well does the Q8300 overclock, or would I be better off risking a used Q6600 off eBay?

If I bought the GTX460, how much difference is their between 768 and 1Gig memory, or am I better off with the HD5770 due to being a crossfire motherboard?

The mother board supports DDR3 1333 would this be a worthwhile upgrade at a later date?

I would like to use the OCUK trade market, but I only have 185 posts after 7 years being signed up :/

Thanks for the suggestions...

Q6600, if you get the G0 version is a brilliant over-clocker and I would say a better choice than the Q8300 - I'd try and avoid the bay though, some of the stuff there is not ideal.

If I "avoid the bay" where else am I going to buy one?

Cookeh said:
CF HD5770's works quite well, but I'd get an HD6850 for your price range.

So, something like this:-
Q6600 ~£80

HD6850 ~£150

Total ~ £230

I had already considered the 6850, but is the extra £30-40 over a 5770 worth it?

If you have a few more pounds, you could get a cooler to aid overclocking

I already have a Zalman CNPS 7800 - it gets the E2160 from 1.8GHz to 3GHz with low temps and the fan running as slow as it can, so I am confident it could get the Q6600 from 2.6 to 3GHz no problem...

Another thing I considered, will the Corsair HX520 cope? I cannay really afford new PSU on top.

Right, after reading reviews, the 6850 is better than the 460 which is better than the 5770, plus it has double the memory bandwidth and newer GPU core, so I am pretty much sold.

Have read that the Q8300 can be clocked to 3GHz fairly easily, and because I know people who have had problems with used Q6600, I'm thinking the extra £20 for a new CPU would be worth it.

Now, I'm confident the HX520 PSU will cope, can anyone confirm this?

Phase 1 complete... I've acquired a Q6600!

Currently;

fsb set to 333 - running @ 3GHz
voltage on auto - CPU-Z/Everest showing 1.38
memory - DDR2-800 @ 400MHz
CPU is sitting at 25'C idle...

Would I be better off setting voltage to manual, and if so, at what voltage? Not really bothered about going past 3GHz!

Just played black ops for about 45 minutes, CPU didn't go above 44'C!

No more in game stutter, no more problems with background sound effects looping, been able to turn graphic settings all up, and fps staying high!

Hi vorticalspace, thanks for your reply.

I have downloaded coretemp, and it says my VID is 1.325. The chip is SLACR G0 stepping.

First thing I did was 3GHz (9x333) with voltage on auto, it blue screened after a long period in game. I have gradually up'd the vcore in the BIOS, and run Prime. Found that with the BIOS set to 1.45, the voltage is reading 1.4, I don't seem to get the blue screen or prime fail.

By the way, your temps are very good

I have Zalman CNPS 8700 CPU cooler - 120mm fan literally running as low as it can, and I have 2 x Akasa Amber light 120mm fans on the side of the case directly over the CPU / GPU, both running slow, and 1 x Akasa Amber light 120mm rear exhaust fan.

Check the chip VID either in bios or by downloading coretemp.
in general, a lower VID will tend to give you a higher potential overclock but with higher temps whilst you may be limited with a higher VID chip.

If I try 8x400 for more bandwidth and higher clock speed, how much higher than 1.4 do you think I will need my voltage to be?

I have noticed I do get a fail in one of the threads in Prime occasionally... but am no longer having blue screen.

jimbobaggies · 28 Nov 2010 at 11:22

Right, running @ 8 x 400 now, raised vcore to 1.4625 in the BIOS, reading 1.41 in CPU-Z.

jimbobaggies · 28 Nov 2010 at 12:34

Bit of a blue screen, so raised to 1.475, now reading 1.43 in CPU-Z.

I have a freind in EXACTLY the same boat as you.

Im building the PC for him and for your info, im choosing him:

http://www.overclockers.co.uk/showproduct.php?prodid=CP-253-AM&groupid=701&catid=6&subcat=1328

(same price bracket as the core2quad your looking at, but better performance)

and a gtx 460, bucase its far betterthan the 5770.

Hi opethdisciple thanks for your reply... but that CPU won't fit my mainboard, and I am not looking to upgrade the whole rig

With regards to overclocking my newly acquired Q6600, I have just raised vcore again in the BIOS due to blue screens running prime.

Bearing in mind @ 3GHz it seemed stable with 1.4volt, @ 3.2GHz I am up to 1.5 volt in CPU-Z. What is the safe voltage for vcore?
