Core 2 E8400 3GHz to Quad?

I'd really like to try and push this PC for another year or so and as I've had it for over 2 years already and added 2GB Ram and changed the Graphics card already I'm considering moving from the Dual core to a Quad, but I'd want at least the same performance, so it would need to run at 3GHz, ideally without overclocking it. Is there such a chip? LGA775 and my board does support 1333Mhz FSB.

Have done a little research and there's only one Quad core CPU using the 775 socket that runs at 3GHz Stock and that's the Q9650 which is over £200! I've had zero luck overclocking my CPU, so I'm not going to risk a slower CPU and trying to overclock that. I'm thinking I stick with what I've got and wait until next year when Sandybridge comes down in price and replace the lot. or does anyone else have any suggestions?

I don't think it's worth upgrading on 775 with the chip prices so high, I think you could probably get a better cpu/mobo/ram combo for not much more!
 
Not really worth buying a quad on 775, go for an aftermarket cooler and ramp ur current cpu - should be good for 3.6 to 3.8 with little effort and put the dollar away for your upgrade.

What trouble are you having overclocking, I have had that board you have got and it is a good overclocker. What speed is your DDR2?

Let us assume you have 800mhz ram, change fsb to 400, add some vcore and you will get 3.6 easy,
if you have 1066mhz you can go even further

Clock speed isn't so important with the C2Q's as they can process more work per cycle as the C2D so a slower speed (Q6600) would be ample to replace an E8400 with :)

Also, as said, what trouble are you having with overclocking? as you can see from my sig, the E8400 can clock very well :)
 
Unless you have got a lemon of a CPU it is more of a matter of learning and understanding a little rather than luck with overclocking your processor.
Perhaps the only thing that you have against you is the four sticks of memory rather than two, more stress on the memory controller. However that shouldn't stop you overclocking the CPU to get some benefit.

I have a P35C DS3R with 2x2GB of OCZ memory. It is running at 8x500mhz, so a 4Ghz CPU speed with the memory divider set for 1000mhz for the memory. It does this speed with little effort on my part in any major tweaking and, AFAIK, most of the E8x00 CPU's would overclock quite well.
I have a Gigabyte GTX460 OC GPU (overclocked) and I run at 1680x1050 resolution.

With the above system there isn't nothing that it can't do in terms of games or anything else that I enjoy using my PC for.

Do a search in the overclocking section and the CPU one for threads related to overclocking your CPU. As the E8400/8500 was, and still is, a popular CPU you will find many good posts on how to go about overclocking.

I know you have written about not wanting to overclock but what other response could I offer when you post in an overlocking forum :D

Only problem I see with overclocking that CPU is 4 sticks of ram, which limited my max stable overclock my I used to own a P35 motherboard.

You should still be able to squeeze a good 500Mhz overclock out of that CPU though even with 4 sticks of ram.

Just increase the FSB, and keep an eye on what the ram is running at and use the ram multiplier to keep it as near to stock speeds as possible.
 
My motherboard is a Gigabyte P35c DS3R and I've looked at guide after guide after guide who have told me 'it's simple' and I've adjusted a single figure, by 1Mhz and the PC refused to boot about 4 times and when it finally did the Bios had automatically restored the defaults. The 4 sticks are a matched set and it did the same thing when I had 2 sticks of corsair ddr2.

I posted a thread here asking for help, checked out the link provided (which no longer exists) but still, nothing. il no booto if I change any of the settings. Once the PC is up and running it's solid as a rock, rarely any crashing, freezing or locking up although i did have a few Nvidia graphics problems but they've gone away since I installed 266.58.

In that thread Rangler (running at 4Ghz) had responded with a request for screenshots of your BIOS settings but you did not reply.

Such settings, and what you did, could be applicable here to help you.

I'm running an EP35 DS3... I can post you by bios settings tomorrow if you like... I know it's slightly different but the basics should be the same, yes?

Also, don't forget that for every speed increase, you (nearly always) MUST have a voltage increase! Otherwise it won't be able to provide the power needed for the speed you're asking :)

It's all trial and error really, there's some science to it but for the most part it's all just 'best guess' and blag it lol :) if it works, it's a bonus! :D

you need to adjust your ram divider first to lower ram speed below normal and then raise fsb. Sounds to me that if you went in the bios and just went adjusting fsb and nothing else then that is where the problem lies. Is mostly everything regarding cpu and ram in the bios set to auto by chance?

Thats a very good idea:). It would also be good if the OP posted bios screenshots for us all to look at

I can provide BIOS screenshots of my current rig running 4Ghz, does more but my ram is cheap (think i maxed at 445mhz).
Had the chip at 4.2 stable but backed off as it made no difference to in game fps.
 
Found a quick one a did when i was thinking of selling it hope the link works, can provide more if required

Just getting my kids to bed now... will post up some pics of my bios settings in about a half hour ok fella :)

Looking at yours, they are slightly different, but for the most part they're close enough :)
