E6750 & Gigabyte P35C-DS3R Overclocking Thread

[mrfatboy]

Thanks for the tip on the new Speedfan

My core temps are now 21C & 25C. it's chilly this morning So I have a delta of 4C between the 2 cores. What is everybody else's delta between the cores? I'm wondering if I did a crappy job on installing the tuniq. Not that it really matters at those temps

 

[darkenedsoul]

I grabbed Speedfan and Temp1 showed as hot and Core showed hot as well, like 54 and 62 which I have no clue what they are referring to at this time. Intel TAT shows cores at low 20's idle. I also grabbed memtest86 (latest) and it says loading.....and sits there and does nothing. I tried it with stock settings after it failed to do anything with a bit of overclocking. I still can't wrap my head around this yet...

I set CPU Host Clock Control to Enabled
Set Host Freq to 353 (to start)
PCI Express to 100
C.I.A.2 disabled
Performance Turbo
System mem mult. to 3.20 (I have 1066 memory)
HS Dram DLL to option 1
CAS timings to 5-5-5-15 per memory specs
rest defaul down to System voltage to manual
DDR2/3 I set to +.3V
PCI-E normal
MCH to +.1V
CPU to 1.33x
Normal says 1.32500V (E6850)

It came up, I set PCI-E to +.1 and system seemed stable, I then cranked Host Freq to 363 and it blue screened on me. Showed 3.2xxGhz for speed though.

I do like the fact this board pretty much sets itself back to a usable state if it detects a problem. I assume others do the same? Wish it had a rear panel reset switch like I think the Asus or Abit has.

Ok, I have system at 3.6Ghz with pretty much the settings up in first post. I have memory at 960 with the 2.40 multiplier. If I go up to next step (1280) if resets the system. I grabbed orthos to see what it would do and output is below.

You are failing orthos which means your system is not stable. it's doesn't like 3.6 now. Try the following.

1) ddr2/3 voltage to +.2 to get to 2.1v(read first post, this board overvolts)
2) set your memory multiplier to 2 (not 2.4) so you get a 1:1 ratio
3) I have not idea what the E6850 cpu volts requirements are. If they are like the E6750 you need to up the volts.


The above is the short cut that may or may not work. You should really start from a stable OC and then work your way up from there. Reread the OP.

Hi, I did set the voltage to +0.2 now to get to the 2.1 reading and it shows 2.11. What I don't like is what I am seeing on the right hand pane of speedfan at bottom of it. the -12V shows -16.97V, -5V -8.63 other two are close (5.21V and 3.12V for +5V and VBat). I'll drop the multiplier down to 2.0 next and do a reboot and see what things look like and retry orthos again. Still keeping it at 3.6Ghz though. This puppy should take that no problem though. Voltage is similar if I recall to the E6750. I assume you want me to up it into the low 1.4x range as well like the original post?

 

[mrfatboy]

I don't have experience with the E6850. If it's similiar to the E6750 in voltage requirements then you probably will have to up the voltage to get 3.6 as in the OP. All of us guys had to do it

don't worry about those speed fan readings. Mine says the same thing. Just worry about Vcore1, Vcore2, and the temps.

What is Temp1, Temp2 and Core referring to? I figure Core0 and Core1 are the CPU core temps. They are within about 2 degrees of Intel TAT which I have up. I set things back to 353Mhz and mem is at 3:20 @1130 (remember I am running 1066, not 800). So this is a bit confusing to me. I tried bringing voltage up to 1.4000 and it reset even with mem set to 2.0 ratio. And I read that with 4Gb it's a bit pickier overclocking that with 2Gb? Not sure if in this thread or not (I think it was mentioned here or over at overclock.net).

Orthos coming up on 10 mins with these settings and running ok. CPU is at 3.177Ghz. If I bump it up by 10 it may still be stable enough to boot. I'll have to check Intel's site on voltage on CPU but I believe it is like 1.5V top end...

 

[Conjugal Visit]

Watching this in almost real time - its weird.

Comment to mrfatboy - I sure could be wrong but given that darkened has a completely different set of components, your advice on memory multiplier might need to be modified. Here's my thinking:

Ram is pc8500 / 1066 - to run that ram at "spec" would require a setting of 533 (533 x 2 = 1066)

CPU is E6850 - default multiplier on this CPU is x9

A ratio of 1:1 (that's 2.00 in the Bios) would result in an effective O/C of 4.797GHz - and that just isn't gonna happen, I'm sure you'd agree?

Regards,

You are setting too many things at once. It's hard to follow and help you narrow down the problem. Set everything to what my OP says. (keep your 5-5-5-15) Let's start from there. Then tell us what it does.

Sorry ;-)

Ok, Here is what I have set in BIOS according to your original post (just what's different):
Host Freq: 400
CPU Voltage: 1.4625
System Memory Multiplier (SPD) 2.0

memory says it's at 800Mhz at the moment. Core temps are mid 20's per Speedfan and Intel TAT.

[mrfatboy]

If he was running 533 FSB (which he isn't), @ 1:1 he would be at 1066. But from what I have read he is running 353. So, 353 x 2 is 706, which is way below spec for his ram but at least we know it should be stable. he than can tweak up from there.

Again, we are jumping ahead. But here is what I would try for a quick and dirty trial

400 fsb
1:1 (setting of 2)
5-5-5-15
1.45 volts cpu
(g)mch +.1v
+.3v on ram

Hi, The +.3V will push the memory to 2.2x volts as I had it there earlier till I saw a post to use +.2V to get me right around 2.1V (2.11-2.13). Everything else is set other than my CPU voltage is at 1.4625. I can drop to lower one if you want.

My core temps are now 21C & 25C. it's chilly this morning So I have a delta of 4C between the 2 cores. What is everybody else's delta between the cores? I'm wondering if I did a crappy job on installing the tuniq. Not that it really matters at those temps

My delta is between 2-3 roughly on the cores. I may have put a bit more of AC5 on that most folks would but it doesn't seem to be impeding anything temp-wise.

 

[mrfatboy]

i'm now using speedfan 4.34 beta 31.


the temps are as follows (at least for mine )

temp 1 = cpu temp
temp 2 - case temp
temp 3- not used
HD - hard drive temp
Core 0- same
core 1 -same

I renamed the last one so I don't know the original name but its for my 8800gts temp.

 

[mrfatboy]

oops, sorry, my bad. too many things going on at once SET IT to +.2v for your ram.

That's been done for awhile now once I saw the voltage with speedfan. Next?! Do we want to private message this instead to keep this from going on too long?

Not sure if you saw but I grabbed the latest memtest86 and burned via Nero the image and it gets to Loading.............. and prompt goes to next line under Loading and it sits there doing nothing.....may have to get floppy image and use my USB floppy for it.

My core temps - 0 & 1 - are always the same. They might vary 1C momentarily, and then return to the same value.

 

[mrfatboy]

Are you using the new speedfan 4.34 beta 31? The old speedfan core temps were the same but this new version has new code for detecting temps.

 

[Conjugal Visit]

No, I'm not using that version. Speedfan 4.33, Everest Ultimate 3.10.1128 Beta, and Core Temp 0.95.4 is what I currently monitor with. All three programs read the same temps, and all show the Core 0 and Core 1 to be the same or within 1C of each other at all times - idle, load, and stress.

 

[mrfatboy]

With Speedfan 4.33 you had to manually add a 15C offset to get the correct temperature tho. The new version is fixed.


I think i did a uneven grease job when installing my tuniq. I not going to worry about it now. My temps are low.

 

[Conjugal Visit]

Yeah, I know about the 15C with Speedfan 4.33, and yes, your temps are quite low with that big bad Tuniq tower!

 

[Shlonglor]

I have a DS3 with an E6300 (1066mhz) CPU. I cooked it to 474 and it's stable at that (RAM fails at 475).

It gets pretty hot, though. I have an Antec 180 case and a Freezer Pro for cooling, which do a pretty good job of venting out the heat produced... but the cores themselves stay at 60-62c when idle, and get to 69-70 with Orthos running (68-69 in Crysis). Measurments taken with Everest and Coretemp (which agree with each other).

Is this safe? I upped the voltage by 0.1 to 1.425 (fails Orthos below that).
I read through the thread, looked at the specifications but I'm really not sure yet.

 

[Conjugal Visit]

Honestly I don't think so - not long term like that. Why not at least enable C1E and EIST in your bios and let your rig underclock both FSB and voltage when you're idle, which is going to be most of the time.

 

[Shlonglor]

I did, but it only goes down from 7 to 6 so it's not a big change. Still stays at the same 59-62c range.
The Tom's Hardware article said that the maximum for this processor is 75 and that the ranges I'm in are fairly ok... what does he base that on?

 

[darkenedsoul]

Well my first test on overclocking ran Orthos Blend for 20hrs with voltage on CPU at 1.4625 with zero errors. So I tried dropping it a couple notches, no-go on boot, went up one, no-go on boot. Set it back to the above and it's back up in Windows. I do have my video card tweaked from 580 to 604Mhz at the moment. I don't know if that would make any difference at this point. Now I suppose I should try changing memory timings? I have 1066 but it's running at 800 1:1 with SPD of 2:00. I will think on this a bit. Maybe I'll bump it to 2.40 and run the test today. Probably 10 hrs minimal since 20 ran fine for first OC.
