My DS3 / E6300 experience....

Hello,

Purely on the strength of recommendations from this forum (

) I ordered a Gigabyte DS3 to go with my other purchases of C2D 6300 + Zalman 7700CU + GeIL 2GB DDR2-800.

Upon setting up BIOS, in the M.I.T settings I did the following:

PCI-Express clock - 100
CPU host clock control - enabled
cpu host freq - 340
multiplier - (left at 7X)
system ram multiplier - 2.0
CPU Vcore - 1.37

And it informed me that the voltages were not optimal. Fair enough, I F10'd my way out of there and the system rebooted.... .... .... ... click, power off.

.... auto power on.. .. ..... .. . .... click, power off
(rinse, repeat)

A few CMOS resets later (tried with different voltages), I discover the only way I can get it to overclock successfully is if I leave voltage control to auto and punch in my desired CPU host frequency.

It's running at 340 now and is stable, max CPU temps reached under load is about 65C, however - wondering how far I can push it and want to seek advice from the ocUK hive mind before going further.

Any ideas why it seems my motherboard won't overclock "manually"? BIOS revision out of the box is F10.

Best Regards,
Dave
 
my ds3 was also F10 and i actualy started OC using easy tune and gave up when i couldnt get past 350 fsb without it freezing. i put my settings into the bios and now its at 422 and happy. doesnt like going higher at the moment though.

i think id be temped to check the voltage in CPU-z and then set it appropriatly in the bios, there is something about allowing something to control that voltage that doesnt appeal.

you may also want to add 0.1v to the FSB and gMCH voltages. also is the geil memoery 2.1v? if you you also need to add 0.3v to the ddr voltage in the bios.

good luck!
 
Thanks, will try tonight. One thought - the clock multiplier options for mine are 7X and 8X. What's to stop me keeping my FSB 340Mhz but changing multiplier to 8X for 2720MHz ?

Cheers,
Dave
 
O.o for the e6300 your optinos should only be 7 and 6 dude. i tihnk the e6400s can do 8 7 or 6.

if you really have the option for 8 then i'd say jump at the chance but i doubt you do.

True, mine goes from 6-8x (E6400)

And yeah, I'm using a Gigabyte P965-DS3 too. Nice motherboard, but I bought a Zalman 9500 which doesn't seem to like my system much at the moment, I think I need more fans. :(

Either way, 120mm on front and another on the back, a fan in the PSU and a Passive cooler on the northbridge with a side fan blowing air directly onto the Northbridge and Zalman. :)

From what I've been reading in a couple places, is that you should try to put a fan onto the Northbridge for overclocking? Apparently thats a bottleneck for the DS3? Correct me if I'm wrong. o.o
 
I never touched that nast house brick cooler on my CPU either, installed the Zalman from stock, pulled the CPU up to 300MHzx8 and was getting temps of about 60 under 100% load on both cores then the alarm went nuts. Don't really wanna risk with 60C+. I heard the C2Ds can go to about 70C and still run smooth, but that'll probs shorten the life pretty bad. :(

EDIT: I never mentioned my specs. o.o

C2D E6400 @(266x8) 1.35v (Stock)
Gigabyte DS3
2GB Corsair XMS2 PC26400
Enermax Liberty 620Watt
Zalman 9500

2x 120mm Case Fans (1x in- front. 1x exhaust - Rear)
1x 90mm Case Fan (1x Side panel Fan - Intake)

what interests me is a direct comparison between old and new 6300s for temps and overclockability. mine is a new one and TAT gives me 10c higher temps under load than coretemp. i havnt really tried pushing past 2.95 aside form pupping the fsb by one, the computer not booting and then setting it back to stock again.i am gradually dropping the voltage though, i tihnk its at about 1.3 now which is better than the 1.456 it was at when i first hit 2.95
 
My main worry is going to far with the Bus Speed, I don't wanna go too far, find I've gone over 60C and getting real close to 70C then knackering my CPU.

On a lighter note, I just got my Zalman to run at 100% all the time using the FanMate2 (had to change some stuff in BIOS > <). Also got the bus speed at 300MHz, I noticed that even at stock bus speed (266x8) it still went past 60C when under 100% load using TAT. Well, it seems its unavoidable and I doubt that I'll really use 100% on both cores anyways. So maybe I could push it further. Any pointers? And yeah, I have read the "Beginners Guide to overclocking".

EDIT: Also I got rid of that annoying "Auto Multiplyer Changer" when your system goes into idle mode. Anyone who wants to know and doesn't already know how to do this with their DS3 motherboard, just set a Manual Voltage. >.>

i just tured fan throttling off in the bios and my 9700 zalman runs full speed all the time now. i tihnk mine now hits about 57 under orthos load according to TAT and 46ish in Coretemp. honestly dont know which one to beleive though.

I'd presume that Core Temp would be far more important, lol. Apparently theres not a massive difference between the two fans, but yeah, I have mine running max now. Unless I wanna sleep, then I could just turn it down a bit I guess, lol

well they are both supposed to measure from the same thing but no one on here seems to be able ti give an answer as to which one is the one to listen to.
 
Personally, I'd go with TAT for two reasons -
1. It's from the manufacturer of the processor.
2. It seems to read higher which means that you are erring on the side of caution. No good getting your temps to below 60 on Coretemp when they could actually be higher.

As for the OPs question - why not leave it on AUTO? My voltages and memory timings are on AUTO and I get a stable 3.4GHz. I haven't tried manually setting anything as I don't need to. Temps are 54C under Orthos load (using TAT).

Thinking about it, I might just have a play with manual settings today and maybe reduce the CPU voltage if I can..........

My voltage is set to 1.35v (CPU-Z read 1.344v) I bumped the bus speed up to 305MHzx8 and now it's locking up etc (blue screen o' death and lockups), think I need to up the volts?

Also... you are supposed to run two of SP2004 right? 1 for each CPU? o.o

What temp would you say is ok for core temp anyways? If I load two and run the Small FTTs on both of them, temp goes above 60 on both cores and my PC starts buzzing. Any suggestions?
 
As I said, I haven't manually set anything except the FSB so can't really advise you on voltages. You may have to raise the vcore slightly - why not give it a try?

As for SP2004, I never use it. I use Orthos which can stress both cores simultaneously - no need to run more than one instance.

Personally, I set myself a target of never going above 60C for the CPU temperature. I am sure it will be fine beyond that but that was the target I set myself. It meant that I had to do a lot of messing about with coolers, fans etc. but I achieved it in the end.
 
Wierd. >.>

I think my voltages are refusing to go any higher than 1.35v and the Bus Speed seems to stop at 304Mhz. > <

Motherboard lets me go higher, but CPU-Z is saying that it's locked at those.
