Is my vcore too high?

[joking]

Configuration:

E6300
Gigabyte DS3 rev 3.3 bios f10
OCZ platinum rev 2 (2x1GB) 6400
Tuniq Tower 120 + Arctic silver 5
50mm fan hotglue to the NB HS

Right now I'm running at 2.8ghz with 5-5-5-15 at +0.2V for vdim and vcore at 1.375V. My temp at idle (tcase/tjunction): 24c/40c. It's running dual prime stable overnight 46c/58c.

Is my vcore setting too high? Am I setting the ram timing and vram correctly?

thanks for your help

The vcore seems a wee wee bit on the high side but still is within reasonable levels I'd say.

When I set vcore to 1.35 then it only boot up to window then restart right away. What did I do wrong or am i missing something?

 

[joking]

The most stable setting that I set is, vcore 1.39375; vdimm +0.2, 4-4-4-15, 1:1. I'm running ds3 rev3.3 bios F10 at 400 FSB by the way.
idle:
core temp 25, 24
TAT 42, 42
TAT 100% load
core temp 55, 55
TAT 68, 68
dual prime for 4+ hours
core temp 45, 45
TAT 59, 59

Althought I set vcore 1.39375 in bios, cpuz shows 1.34, speed fan shows 1.34, ez tune shows 1.38.

Is there anyway I can lower the vcore while maintain stability? if so what setting should I change?

thanks a lot.

Go to 4-4-4-12, your Vcore is fine, but Core Temp is giving you a -15c offset. Re-read the Core 2 Duo Temperature Guide, (updated earlier today), download SpeedFan 4.32, and you can correct your Tjunction offsets.

Hope this helps,

Thanks CompuTronix,

My ram is rate 4-4-4-15 at 1.9-2.1v so if I go to 4-4-4-12 do I have to increase vdimm?

Yes, I run speed fan 4.32 for those temp measure.

I have read your temp guide (old version) many time before I start OC, very well detail by the way. Will take a look at your new update.

Thanks.

Tras timing of 12 is typically correct for 4-4-4 timings, and should not require any tweak to Vdimm when decreased from 15 to 12.

Couple more questions, when people said they setting vcore at stock voltage does that mean they set it at 1.325v or just leave it to auto as default?

At 2.8ghz on my E6300, the most stable vcore is 1.3925 or 1.4 I can't go any lower without system unstable. Does that mean I have to settle with those @ 2.8ghz?

When I OC my to 2.8ghz if I leave the vcore as auto the bios flashing the green message "system optimized" and I see the vcore in ez tune is 1.41v. But if I set vcore to manual @ 1.3925v or 1.4v then the bios flashing red message "system is not optimized".

Overclocking is best accomplished with manual settings, but many users fail to appreciate the need for attention to detail, and don't bother to define their settings.

Unless you have enough thermal ceiling to increase your Vcore, then yes.

When I OC my to 2.8ghz if I leave the vcore as auto the bios flashing the green message "system optimized" and I see the vcore in ez tune is 1.41v. But if I set vcore to manual @ 1.3925v or 1.4v then the bios flashing red message "system is not optimized".

Again, overclocking is best accomplished with manual settings. Ignore the message, and go foreward.

wow That clear up a lot for me CompuTronix, thanks.

I'll test some more probably increase the mch and fsb voltages to see if I can lower my vcore @ 2.8ghz and run stable.

If I have some question along the way. I may need your help again.

If your goal is 3.0 Ghz, keep in mind that it will require an increase in Vcore of ~ 0.100 volts, which will put you at the recommended limit ~ 1.5 volts, which in turn, will push all CPU temps up ~ 7c. Depending upon ambient temp, you may not have enough thermal ceiling. When running TAT, remember the following:

Parameters

(F) Tcase Load should not exceed ~ 55c.

(G) Tjunction Load should not exceed ~ 70c.

My goal is 2.8ghz for now. I just want to see if I can lower my vcore and run stable. Yes I monitor my temp closely both tcase and tjunction.

I run dualprime overnight last night and tcase (46, 45) in coretemp, TAT shows (62, 62). So I'm at the warm level with vcore 1.4 in bios

 

[CompuTronix]

tcase (46, 45) in coretemp, TAT shows (62, 62)

Tcase is the single CPU temp in SpeedFan 4.32. Both Core Temp and TAT read from the same dual Tjunction sensors. TAT is correct, and Core Temp is obviously offset by -15c. These temps are shown in SpeedFan 4.32, and are probably offset to the same values. As I pointed out in a previous post, this can be corrected:

Go to 4-4-4-12, your Vcore is fine, but Core Temp is giving you a -15c offset. Re-read the Core 2 Duo Temperature Guide, (updated 3/5/07), download SpeedFan 4.32, and you can correct your Tjunction offsets.
