Possible for any more?

Hi Guys.

Well as some of you may know, I've been trying to overclock my new Intel rig. First time owning a Intel, was on a AMD 754 3400+ for four years.

Current setup now is:

Intel E4400 @ 2.90Ghz
Gigabyte GA-945GCMX-S2
2 x 1GB Chaintec Apogee 667 memory,
LC-B500AT 500w PSU.

Now, I've gotten this E4400 to 2.9Ghz, stable. Tested with Super PI and Orthos for a couple of hours.

However when I set it to 300 x 10x (3Ghz) the pc won't POST. .

I had my E6300 at 310 x 7 - stable. So memory can do the 300 fine.

No I'm not too sure what's the problem here. I pushed the Vcore of the E4400 to 1.4V, still nothing. .
Memory is at 1:1 ratio as well.

Here are some screen shots of CPU-Z:

I think you might need to up your northbridge voltage.

 

[Priapus]

Ah, that's an idea. I didn't think of that.

Will give it ago now.

Thank you.

 

[Priapus]

Okay, not too sure what happened...2.95Ghz. Seems to be be voltage issue as this PSU undervolts by 0.5V. So might try upping it more..

 

[Priapus]

2.95Ghz seems to be stable now. More testing. If I can just get it to 3Ghz, I'll stop and be happy there.

 

[Priapus]

Spoke too soon. Locked up in Windows. @ 2.95Ghz.

 

[ChrisD.]

Try reducing your RAM timings to 4-4-4-12.

 

[Priapus]

But the ram run fine at 310mhz on the E6300..., take it CPU at 3Ghz needs it to be redused?

 

[ChrisD.]

No, reduce the RAM timings. I think that your system is locking up because the RAM is running too fast with too fast timings.

 

[Priapus]

Okay, fair enough. I will try that just now and let you know.

Many thanks.
Rob.

 

[Priapus]

Still locked up.

I got one of these CPU's too in the last 2 weeks, it wouln't start resembling stable @3ghz untill 1.4375v, and wasn't really stable till pumping 1.45v into it. that was 333x9 or 300x10.

On the other hand it ran soo much cooler at 2.66ghz with stock volts, so i just droped the multipliers tweeked the FSB which also appears to brickwall at 345MHz on my E4400, anything faster and it won't post and 345mhz is stable.

I'm running a Gigabyte P35-DS3, and with other CPU's this board can go much higher on the FSB.

Simply put recent batches of this cpu simply do not clock as well as other c2s or the quads.

 

[Priapus]

Well, I am happy at 2.9Ghz then. My E2140 and E6300 where never good at 2.4

 

[Rackerz]

Is there an option to drop the multiplier from 10x?

 

[Priapus]

No, unfortantly not.

 

[SBD]

Well my E6750 seems to love high clocks, i manage to get into windows and tested @ 3.6 Ghz (450 x 8) but im leaving it at 3.0GHz untill i get better cooling hehe as i have a stock HSF lolz

 

[SBD]

Maybe try 1.4V if you have the cooling and make the ram timings silly like 5-5-5-12 or something just to make sure. I havent clocked a E4400 but they must do more than 2.9Ghz :S well i would hope so. If u "need" more then get one of the G0 steppings as they clock so much better hehe

 

[mame]

more ram voltage? also.....

2.95Ghz seems to be stable now. More testing. If I can just get it to 3Ghz, I'll stop and be happy there.

I've said that to myself many times. Would only turn into "well i managed 3ghz, if only i could get 3.1ghz" But thats the attitude you need to get anywhere overclocking
