E6750 Finally Arrived!

[bryanW1995]

are you still at 1.6v or did you dial it down a bit when you went to 3.85? I had to use 1.64 in bios to get stable at 3.704, and even that I was afraid to run orthos for 24 hrs +.

 

[jhl81]

yeah i would be scared to ... i'm not on 1.6V now, that was just to see how far i could go with that voltage right now i'm at 1.45Vbios my board vdroops around .04 looking on speedfan and everest i'm at 1.39load so i think i'm pretty safe? I'll probably stop my test around 12hours and sreenshot. i'll start gaming after that been over a week testing this thing probably oc more when i get H20 setup which won't be for a while ...

 

[bryanW1995]

if you're at 3.9 on air then h20 will probably be overkill, anyway. I was going to go water this time but didn't want to deal with the hassle.

 

[jhl81]

yeah i guess so ... i'm pretty lazy as well so i won't be using h20 for long time maybe when i get quad later down the track. I opened my case and i got better temps doing small ffts here some screenshots, hope the info in there will help some ppl out there

this one doing blend at 3900mhz i stopped this one yesterday

[dctrmas]

hmmmm.....I need water cooling

 

[bryanW1995]

thanks for the screenshots. now I can kill myself b/c I know that you weren't full of S***! swtethan get's an easy 3.6 on his Q6600 and you get an easy 3.9 on your e6750...good thing I don't actually NEED anything faster than my old A64 3700+ or I'd really be upset...

I'm currently running 3.566GHz (509.5 x 7) 1.475v, ram @ 1019MHz 4-4-4-12. It has been ORTHOS stable for 40m so far...I am very happy with the 509fsb on the board. Temps under load are around 56C.

I was able to run ORTHOS without error @ 3.7GHz (462x8) 1.525v, ram 1066 5-5-5-15 for 1:38hrs before I stopped it since I don't want to run the voltage that high for long periods.

bryanW1995: I know how you feel, we need to find jhl81 and beat him with a stick :laugh:

 

[bryanW1995]

damnit! he doesn't have his location info set up yet...he's probably gordon moore's grandson or something...

 

[cmdrdredd]

After a certain point, depending on what you're doing there is a diminishing return on the speed. I mean. 3.6Ghz to 3.9Ghz is not that big of a difference all things considered.

 

[jhl81]

damnit! he doesn't have his location info set up yet...he's probably gordon moore's grandson or something...

LOL gordon moores grandson! thats a good one :laugh: i was feeling like this wit the e4300 when other ppl claimed that it would go avg 3.4ghz and ppl claiming that they would hit 3.6ghz on air and i could only just get 3.2ghz stable ... to think of it the only diff i would see in real life apps is very minimum with what i do, like cmdrdredd said ... after 3.5ghz i couldn't notice anything much except in benchmarking which are no value in running everyday apps ... the big difference i saw was when i moved from am2 3800+ windsor running at 2.5ghz which even that ppl were hitting up to 2.8ghz .. so out of all the chips i bought during those years i think i atleast deserve one good one right?

Hmmm...okay we will let you off this time...

Tried 510.4 x 7 (3573MHz) 1.475v, ram 1021MHz 4-4-4-12 - but it errored in ORTHOS after 2h11m. :|

Currently running ORTHOS @ 504 x 7 (3529MHz) 1.4437v, ram linked and synched @ 1008MHz 4-4-4-12 2.175v - stable for 21h33m so far.

I've decided not to bother going much higher due to diminishing returns. I'm already gettting 12,000 in 3DMark 06, 200 or so points isn't worht the voltage. Might start playing with the memory now....

 

[ThorAxe]

Oops.... double post

 

[nCred]

My e6750 with a Gigabyte p35-ds3r seem to be orthos stable (only tested it a few hours though) at 3400 mhz. vcore set to 1.375 in BIOS, but it drops all the way down to 1.296v under load. I was worried my poor 350w power supply couldnt take it but it´s working good so far.

edit: Also stable at 3.4 ghz with 1.35v i bios, cpu-z shows 1.28-1.296v.
edit2: and 3.4 is also stable at stock voltage (1.325v), tested for 3 hours in orthos so far, I´m suprised it works since the voltage drops to 1.25-1.26v.

 

[ThorAxe]

You should be okay provided your PSU has a good 12v rail and your video card doesn't take too much power.

Just testing 7x505 = 3.538GHz @ 1.4437v, ram @ 1010MHz 4-4-4-12. ORTHOS stable for 18 hours so far...

nCred: That's a great overclock for your voltage.

 

[bryanW1995]

why are you going for 7x500+ instead of max oc? Are you getting better voltages? Are you having trouble getting 8x438? You are putting a lot of unnecessary stress on your mobo right now, though it is kinda fun (or so I hear ) to check out max stable fsb.

it's less stress to run 500Mhz 1:1 than 430Mhz 1:1.20

Less stress on what ?

It seems to be more stable and require less voltage. Also Everest read, right and copy scores are much better.

As I said previously, I was able to run ORTHOS without error @ 3.7GHz (462x8) 1.525v, ram 1066 5-5-5-15 for 1:38hrs before I stopped it since I don't want to run the voltage that high for long periods. However my benchmarks were not much better and in some cases worse so I don't think the additional voltage is worth it.

The northbridge & memory controller.

 

[nCred]

ok, I´m up to 3600mhz stable, but the northbridge heatsink is really hot. Good news is my CPU only need 1.3875v ("vdroop" to 1.312v under load according to CPU-Z). If you want to avoid vdrop, dont buy a P35-DS3R i guess..

It makes a difference to people in 2nd place.

BTW, When is Thermaltake coming out with their LN cooling system?

wow that 's alot of vdroop ... well i have a problem with the northbridge getting too hot as well on my 965p-ds3p but after i got a fan it made a hell of a difference its actually warm to touch (its not hot at all) ... and also coz i had no air going towards the mb aswell it made it hotter .... i can't fit an aftermarket heatsink coz of my tr ultra so this was my best solution but works and cools my cheap ram aswell and gets my mb temp down too ... notice i don't have the fan attached to the nb heatsink but still made a heap difference ....

see the link here to see how i got the fan ...

http://img504.imageshack.us/img504/5576/spa0165he6.jpg

this is what i'm at right now and even at that point of orthos the northbridge was warm not hot ... before i had this fan the northbridge was hot to touch even for a second ...

http://img411.imageshack.us/im...0mhzscreenshot5lt8.png

i think it was a good investment .... unless you already have cooling on it and its still that hot?

I do not have a NB fan but Im a bit worried my temps are too high anyway, if I look at the idle system temp in BIOS it says 47-48c even at stock speed 8x333 while the CPU temp is much lower. On the other hand, the system is stable in orthos even at 7x475. Everest reports much lower motherboard temps, around 32c idle.

For me when the northbridge got too hot the system will reboot itself without giving errors in orthos maybe 15hours in.. i knew it was the northbridge as it was so hot i couldn't touch it ... after the fan no probs system runs very smoothly and noticably more stable than before 24hrs+ orthos rock solid ... if you don't have a nb fan and you are worried that its getting too hot i think you should invest in one or use another cooling method to cool it down .... after all we are pushing the cpu which also is pushing the nb, cpu might be working very stable but that doesn't mean the nb is not getting any damage along the way aswell, right? comparing to my e4300 the northbridge runs alot hotter probably coz of the high fsb on these, we are very cautious of cpu temps and stability and usually don't use stock hsf for cpu for ocing purposes but alot us disregard the nb which is just as important imo ... but from reading its seems you have a very good chip aswell gl

 

[nCred]

yeah, it seems like I finally got a better than average chip. I think I´ll just keep it at 3.4 ghz stock voltage until i get better NB cooling, it´s still a lot faster than I actually need.
