big difference in c2q q9400 vs. OC'd c2d e8400? UPDATE: installed c2q 98C temp?!

[slightlyhuman]

i have an abit ip35e and am trying to avoid a total system upgrade a little longer.. i've got my eyes on either CPU. the wolfdale is about $20 cheaper. i'm pretty sure my mobo and ram i have now will push the wolfdale pretty good considering it's got my e2140 @ 3.0 stable on air.

would the performance between both cpus be night and day differences? main purpose is games.

update: just installed the c2q.. booted into bios and checked temps(stock speeds). it said 98C. I shut it down. checked it again, 98C. I then removed my heatsink(artic cooling pro 7) then used the stock heatsink and got the same 98C temp. it even froze while in the bios a few times..

wtf?

For games/apps that take advantage of quad core, the Q9400. For everything else, e8400 hands down. You can still overclock that Q9400, just won't get as much out of it.

 

[PlasmaBomb]

It depends on what speed you want to hit.

The Q9400 should go to mid 3's, don't know how good the ip35e is...

 

[slightlyhuman]

the ip35e is a really good over clocker. hopefully i'll get a decent clock with the quad.

Warning: IP35-E is known to degrade with increased PWM requirements from the quad. Read up on the issue.

PWN? have no clue what the hell that is.. care to elaborate or link?

I think it's the power to the CPU, but yeah, I'd just go for the quad.

Which games? Some games are so graphics intense that the difference would be small-to-mininal. Other games are CPU heavy, and can benefit from higher clock-speed, larger cache, or more cores. All depends on the app and the settings used.

Quads are harder to run slightlyhuman as their greater power requirements put additional strain on the power circuitry of the board, potentially limiting the OC. That said there are people out there with 3.6GHz from the Q9400 on this board...

thanks plasma! and the game is bad company 2. i'll be happy with if i can get it stable to 3.0ghz. we'll know today hopefully.

surely my 500watt rosewill will be enough? only running 2 HDs, 1 DVD, gtx 260.

Last but never least, don't skimp on the PSU. If it says Rosewill, you're skimping. Your OC may start off ok, but if you get instability that PSU would be suss.

I had a q9400 that ran happily at 3.75 ghz. Could go to 4.0 with lots of voltage. Your mobo will need to be a pretty good clocker due to 8X multiplier. 3.0 won't even make it sweat. Good chip.

Edit: I'll also add it was on a GA-EP45-UD3P a overclocking beast of a mobo.

AT this point, it's hard to justify upgrading to a dual core. Go for a quad processor.

 

[slightlyhuman]

i have an e2140 at 3.0 right now with this board. it's a good board. and rosewill isn't antec, etc but they do make decent products. at least there are plenty of reviews on(good reviews) on the PSU i choose. BUT i wouldn't be surprised if the quad did push the psu a little too much.

Do you know how to put a heatsink on? Not being sarcastic but even if the heatsink was slightly on it wouldn't get that high.

 

[slightlyhuman]

yes, i do. i just put my e2140 back in there and also my other core 2 duo chip in there. 29C.

i've tried 2 different HS/F. Stock and aftermarket. i'm thinking it needs a bios update to recognize the CPU...

 

[RussianSensation]

Always make sure you have the latest BIOS before installing a new cpu. It may be reading the sensors incorrectly.

 

[slightlyhuman]

well guess i flashed it correctly somehow. the temps went down and i ran bad company 2 for a test run. ran awesome. it did locked up and reboot on me. ofc i had the stock hs/f and when i got back into the bios it was 90C. this thing sucks! putting my aftermarket back on to see how much cooler it will run.

i STILL have the dreaded double boot problem that ABIT chipsets are notorious for. not sure what the fuck i'm doing wrong there. i installed the lastest bios..

 

[slightlyhuman]

at 3.2ghz with just a tad bit bump in vcore. jesus this cpu screams.

 

[Hyperlite]

Use CoreTemp to monitor temps in windows. If the stock cooler is giving you 90C at idle the aftermarket still isn't going to bring the temp down into a safe range. If it idles higher than 60 or 70, it's almost guaranteed to crest 100C under load, at which point it WILL throttle or just shut down. That's probably what caused the lockup. You need to stop stressing it and figure out if these temps are real or a reporting error.

 

[slightlyhuman]

it was a bios error. running 3.2ghz at a cool 42c

I have the same mobo.. I am glad your chip is a winner... however don't go to crazy as I don't trust the mobo with a high quad overclock.
Its a winner with dual overclocks but I have noticed that the newer motherboards seem to be heavier and better built.

I did burn up one motherboard that was a winner for dual overclocks.. Biostar T-Power. It just couldn't handle the quad and died a couple of days into the overclock. This same motherboard is a champion overclocking duals.
Lucky for me the mobo was new so I exchanged it for a Gigabyte board and have been very pleased.

I assume that like myself, you only paid about 50ish for the board.. worst case senerio if you fried your board is not bad because it seems that socket 775 boards have dropped in price.

At any rate.. HAVE FUN WITH IT!! Because that is what overclocking is about. You already know there are risks.. Its just now and then a pest like me pops up and puts a damper on your fun by reminding you of said risks.

Peace

[slightlyhuman]

for sure rich! that's the name of the game! just got done playing bad company 2 and it never went over 55.
