My DS3 / E6300 experience....

Alright; i'm cookin' on gas. Now overclocking manually (think it was the RAM timings/voltages that I hadn't checked).

my G-skill DDR2-800 RAM is rated 5-5-5-15 and 1.8-2.0V so i've left that at +0.2V. CPU set at 1.27V at the mo over the default 1.225 so going to do a stability / temperature check then start ramping it up...

400x7 should be obtainable on 1.375v or so.

Just keep an eye on your temps. They seem very high for your overclock at only 1.27v.
 
What cooling are you running? 72C is getting into the danger zone for throttling. It won't harm the processor, but it will slow itself down to reduce the core temperature, which totally defeats the object of overclocking.
 
I've taken it back a bit down to 365*7.

My cooling setup is as follows:

Coolermaster aluminium case
Zalman 7700Cu @ max fan rpm
2x front intake fans (not very efficient...)
1x top intake fan (bringing cool air directly next to CPU)
1x exhaust fan (all 80mm)

Something's strange because the air coming out the exhaust fan is.. lukewarm, despite my CPU currently sitting at 67C under stress load.

Now I'm no stranger to overclocking (ahh days gone by of Celeron 300A running at 450MHz) and have fitted maybe 20-30 different HSF's in my life, so very confused about what's going wrong here. I've been out of the loop for a while right enough, did this game change somewhere along the line? :)

I take it you've applied thermal grease to the bottom of the cooler? :p What voltage are you putting through the CPU? You really dont need a huge vcore bump for C2D - but you do on the chipset voltages.

Is the CPU perfectly flat? some have been reported to have concave IHS'
 
Cob: I'm now thinking about an upgrade for sure...

trojan698: Yes :p I tried to get AS5 but put on some cheaper Akasa stuff - claims to be just as good ("Silver based high performance thermal compound").
I'm running it now at 1.264v and 2548MHz (364 FSB), how fast do you think it will go at this voltage? Currently running the chipset at +0.1v, should I bump this up?
Regarding flatness... didn't pay any special attention, but seemed to be flat enough for the HSF to go on.

Well well!

Now running stable at 2.7GHz (385x7 @ 1.28v), idle temps are <50C and under load it maxes at 66C. Happy with that to be honest until I can get some better cooling...

SuperPI 1M completes in under 21 seconds, yee haw.

Thanks to all for the advice, it's been an enlightening experience!

Well done for not getting totally hacked off and spitting out your dummy :p

When you get the better cooling, you'll be in good shape to go to 3.2-3.3GHz and your target SuperPi times should be in the high 17 seconds. SuperPi is also excellent for tweaking your RAM timings as it is highly sensitive to RAM speeds. If your RAM is still on AUTO then it's well worth trying to tweak it now. It can be worth as much as a whole second off your time.

Keep us informed of how you get on though, as there is a healthy amount of voyeuristic 'clocking that goes on once our owns rigs have been maxed out :)
 
Deffinatly cooling holding you back.

Using a Scythe Ninja I get 28C idle, 53C load, and run 476x7 (3.33Ghz) on 1.375V. :)

Only a short Orthos run, but its 100% solid (done a long run in the past), and temps never vary much from that no matter how long you leave it.

Got mine sitting at 350MHz x8 at the moment, seems to be running smoothly, although it could use a voltage boost in the next couple of MHz it seems.

I sorta set it to stock settings because it was getting hot, then realised the grill on my PC was stopping good airflow, so I just opened the door up (I have a Soprano case with the door that comes off it's hinges :))

I think now I could probibally go higher into the 3.2GHz if the voltage increase doesn't cause too many issues.

Idle: 37-36 & 34-33

TAT 100% Load: 74+ & 72+
ORTHOS Priority 9: 66-67 & 65-67

Those temps are pretty good in my opinion and when running Oblivion, Battlefield 1942, BF: Vietnam, BF2, BF2142 and Source games, the temps barely go above 52°C. So thats made me really happy. :)
 
Currently running 450x7 (3.15GHz) with my Geil 2GB PC800 kit running 5-5-5-15. Have just modded my Scythe Ninja HSF due to the known issue with it making contact with the capacitors on the DS3 and got a 5-8 degree temp decrease - going from 40 down to between 32-35 idle.

Very pleased indeed and glad i did the mod, havent tried really pushing my system yet, will have to see if can get up to the 3.4/5 GHz mark.

Only got +0.2V on the RAM set in the BIOS, may need to increase though if go any further.
 
what ram is that schumi? Had to give my G.Skill +0.4v to get 3.15Ghz wont go any further either, though i havent played with anything else to see if it would go.

Edit: doh u said Geil in your post, ignore me im stoopid.
