2 e6300's that seem to be good overclockers

[zbomb5610]

I received 2 e6300's. I was fed up with the 475 fsb wall of my previous L632A e6300.

L627A

L628A

those are the weeks, both are b2 steppings (SL9SA conroes)

I just started playing with them so i don't have enough time to actually find out their stabilities, etc.

I was able to get the l627 to roughly 3.75 w/ 1.46v on stock air cooling and just ran cpuz before trying to push the cpu harder and having the comp reboot. Super Pi hit 16.9 seconds for 1M.

I was able to get the l628 to roughly 3.65 w/ 1.46v on stock air cooling and ran Super Pi 1M for 16.3 seconds, weird that it did super pi faster at a slower speed though.

I only need one of these processors so I will play with both and figure out which one i want, the other i will most likely get rid of since i don't need 2.

Just thought i would post initial oc results, should hopefully have some screenshots and more tests in the next couple of days.

Gigabyte DS3 rev 3.3 mobo
No name D9GCT memory (2 x 512 running at 2x multiplier)
Stock Intel Fan

At stock volts, i hit around 3.1-3.2 which seems pretty stable with some testing, but i need to run orthos for longer.

I did find that at stock voltage however, when i ran orthos, i would get temps around 69, and voltage above stock would yield temps in the 70's, is that normal for these conroe cpu's???

Any other pointers that people think i should try while testing these processors out are welcome.

I do have a scythe infinity heat sink that i need to install, but i don't want to install it and keep on switching cpu's, would be a pain in the butt.

Here is an initial screenshot of the l627, it actually did super pi 1M faster than it did previously, so i guess whatever i said above about it doing it slower at higher speed isn't true.

I would say any Conroe temp over 65C for any prolonged period is not so good. Ideally under maximum load it should be hitting no higher than 65C...although some enthusiasts run them much higher.

My E6300 is at 63C idle @ 520FSB = 3640MHz with 1.44 vCore. I did the SuperPi 1M in 15.985 sec. This slight improvement over your zbomb may be attributable to my ram timings of 4-5-5-5-12, which got it below 16 sec.

Obviously my cooler is unsuitable for such high overclocks. I backed off to 470FSB @ 1.30v, and the idle temp is about 45C. :)

What cooler are you running, and i know you saw the temps were hitting mid 70's under full load, that was just a quick suicide shot, but i have my infinity cooler on the cpu now and i am working on getting stable at 3.5 with 1.47v hopefully. Trying to keep the temps from going over mid 60's.

Seems like you have a good e6300 there. I would just be happy at 3.5, especially since my last e6300 wouldn't even allow me to get over 3.2 with the fsb wall it had.

zbomb, most guys at [H]ard Forums will say that it's just luck to get an e6300 that clocks over 3.5Ghz, I think many of these can go up to 3.6 as I've done 3801mhz SuperPi 1M on air - maybe I'm wrong. When you were stuck at 3.2 did you have the same MB, rams, and settings as your 3.7ghz chip?

Xvys, you using stock HSF? At 3640 mhz with a Tuniq 120 mine idle at 41C with fan set at Low and 33C fan at High with no lapping. I game all night at this speed. Nice ram timings btw!

Oh and here's a screenie of my 3640 for your comparison.

and some ppl say the cpu's have nothing to do with fsb walls :rolleyes:

Only thing i have changed around is cpu's, so first e6300 stuck at 3.2, got the other 2 e6300's, same setting and everything, and they were able to get over 3.5

I am currently running orthos at 3.5 w/ 1.475 vcore and it is stable after 2 hours so far, so hopefully it stays stable until i wake up.

Also, are you going by temps on core temp? I use intel thermal analysis tool since it seems more realistic to me (core temp always says it is a lot lower than it really is but maybe i have a version that doesn't read it correctly).

And people that say cpu fsb walls don't exist are full of bs, i have played with more than one cpu that has had an fsb wall, and you know that is the case when the only variable you change is the cpu and it will run at higher fsb.

I also don't think i have the scythe infinity mounted incorrectly, since i tried to do the modified mounting technique and had to rig it while getting it to tighten (didn't have the correct bolts/nuts to get it on correctly). But even at 1.475 vcore, it isn't going above 70c with the infinity mounted incorrectly.

My TAT at idle shows +2C over Core Temp, and at full load TAT is -2C over Core Temp.

Post your results in the Conroe Overclock Database if it psses 8 hours Orthos, E6300 needs more entries...

I will, my goal is to lap the cpu, lap the heatsink, do better mounting of the heatsink, and i am going to try to hit 3.6 stable minimum, would be nice to hit 3.65 stable.

Maybe i just have a crappy version of core temp.

Don't know what those people are smoking, because i have a e6300 which hits a VERY hard wall.
It can do 3.2 at stock volts all day/night long. BUt anything over that, forget it. Regardless of what voltage you feed it, it will not budge.

I have tested the mobo and it can go 520plus easy... it's the CPU that hits the wall

yeah ihad a E6400 L624A hits 425fsb wont boot any higher, tried it on 975XBX, 965P-DS3 , EVGA 680i nada, wont boot at 426fsb at 1.6v

I'm using a Thermalright Mtt6775 heatsink with copper heatpipes. It is designed specifically for the LGA775 with the four push-pins. It's a new design and I think in the reviews it's idle temps were just slightly better than the stock cooler, but is much better under load. It was on sale for $25, but I soon realized it was not up to snuff. I was going to return it, but waited too long, so I guess I'm stuck with it. But it's fine for 470FSB (with ram timings of 4-4-4-10).

Yep, the Crucial Ballistix PC6400 ram did the trick. I previously had some OCZ ram that would only do 425MHz with all the same settings. So the ram is the key. This Crucial ram is registered in CPU-Z at 500MHz 5-5-5-12...so it's "forward" compatible to DDR1000...Not bad for DDR800 ram I bought used on Ebay!

I've hit a wall, my P5B Dlx won't go over 533 fsb, my rams are good upto 550 and I can push 3.8G with Clock Gen. Gotta find a way to get past 533. I will be doing the search but If somebody knows... I'd appreciate some advice. Thanks.
