The most likely explanation is that when you went to unlinked, it rounded the FSB on the RAM downwards, hence it booted.

they were reporting 475:475 in cpu-z when unlinked and linked -sync mode and cpu-z was reporting it as 1:1

just seems wierd 1:1 didn't work when set in bios.

what is the difference between 1:1 and linked - sync mode?

Isn't 1:1 literally that - 1066MHz QFSB=1066MHz RAM FSB, sync mode runs the RAM at half the speed of the CPU (1066MHz QFSB=533MHz RAM FSB). They seem to think we must be using RAM that is stupendously fast given the linked options.

Thats really very low temps, you could probably save your ears a bit and turn it down I reckon :) It does bode well though

Yeah, I turned it down to the noise level of my 120mm exhaust fan, which is still a bit noisy, but too bad (roughly 1600rpm on the tuniq fan). Temp went up about 1-2 at idle and only 1 under load. Looking forward to see how hard I can push the OC. :)

Any starter points or tips for an E6300 (like WJA's example for the E6400)? Or rather than ad verbatim, just what would be different, as i've already got a printout from the 4300 example! ;)

ok, so I've done a bit of initial testing with the ocz and the highest stable 1T so far was at 366hz

some results

Superpi 1M

mem unlinked unless specified
cpu 3.8 = 475x8

3.8, 400 mem 4,4,4,15 2t = 16.172s 5CD7BFE8
3.8, 446 mem 4,4,4,15 2t = 15.859s 8E94C3A1
3.8, 476 mem 5,5,5,22 2t = 15.938s 8492F0A9 (reported as 1:1 in cpu-z but unlinked in bios)
3.8, 476 mem 5,4,4,12 2t = 15.766s 798DBC91 (linked- sync mode)
3.8, 476 mem 4,4,4,12 2t = 15.610s 14083412 (linked- sync mode) UNSTABLE
3.8, 264 mem 5,4,4,12 1t = 16.812s 798DBC91
3.8, 333 mem 5,4,4,12 1t = 16.172s 5CD7BFE8
3.8, 349 mem 5,4,4,12 1t = 16.141s 5CD7BFE8
3.8, 366 mem 5,4,4,12 1t = 15.937s 60F40661
3.8, 366 mem 4,4,4,12 1t = 15.828s A93017DE

I will run some 32m comparisons soon

Hows the heatsink contact with the cpu?
Click to expand...

The Tuniq's as screwed in as it can possibly be, the retention H-bracket looks evenly bent around the corners, looks like there's plenty good contact. Maybe I messed up application of the ceramique? Followed the instructions with putting a small line down the centre of the processor die. I installed the tuniq by myself so it was pretty awkward and I think it wiggled ever so slightly when I was screwing in the first corner, not sure if that'd really affect it though?

Maybe I just need to let the thing bed in for another 24-48 hours before ramping up the OC? Am I just being silly or is going up 6 degrees idle and under load OCing from 1.86 to 2.1 GHz a lot?

The contact is most likely fine then. Is it possible you put too much TIM on the cpu? I always put about a grain of rice (once boiled :D ) on and then put a clean plastic bag over my finger and spread it around in clockwise and anti-clockwise circles until it's fine and even. The old school of thought (which I still adhere to for my builds) is to do the same with the heatsink aswell and then clean it off again to fill and microscopic holes. The difference is minimal but atleast you know you have done it right first time.

Try that, let it bed in for a day and see what the temps are like at, say, 2.75ghz?

Hey, thanks for that... Yeah I already tinted the CPU with TIM by doing as you say, blobbing out a little compound and rubbing it over clockwise and anti-clockwise with my finger in a plastic bag, then cleaning it all off. I didn't do the same for the CPU though, I did the thin line of compound in the correct direction. Think it'd make better contact by just spreading a thin layer over the CPU instead?
 
It's very subjective but I'd say deffo. Spread the stuff around then when you put the hsf on give it a put of a wiggle before bolting it on. This should get rid of any air bubbles in the middle.

Some people recommend the line technique as you don't get air bubbles in the middle but you can sometimes get honking great big gaps at the edges and too much tim in the middle.

As I said, it's all very subjective.
 
I'm gonna order Asus P5N-E very soon and I'm curious what is the size of the NB heatsink? Heard they get very hot so I think cheapest choice is to slap a fan on top of it. And can some of Asus P5N-E + Tuniq owners tell me if there room to fit this heatsink with a 70mm fan on top of it? ty
 
There have been loads of threads about the new recommendation to put a line down the middle, but what I reckon it really comes down to is this;

1. You could have a dished/concave IHS, in which case reapplication isn't going to help.
2. You could have poor contact between the IHS and the cores, in which case reapplication isn't going to help.
3. You could have very poor airflow in your case where either the CPU fan is being starved of air or the air it gets is hot air, in which case reapplication isn't going to help.
4. When you re-apply the thermal interface material (TIM) you could damage the motherboard, processor or fan, which isn't going to help.
5. If you have followed the common line of advice and turned on the extra +100mV then you are having to disappate 8% extra power from the processor. You are only applying that extra 8% voltage to make up for a droop at times of high power requirement. If that requirement isn't there (eg. in your low overclock) that extra voltage/current/power has to go somewhere and it's lost as heat. It's a possible reason why you are running so warm at such a low overclock, and again, reapplying the TIM isn't going to help.

47C under load isn't a bad temperature. Leave it a couple of days. I'm fairly sure it will settle down. You could always follow Big.Wayne's example and set up outside on the balcony on the coldest night of the year so far to get a REALLY decent overclock ;)

yeah I've seen that pic, but i want to know if it will fit with a tuniq cpu cooler cause its a lot bigger than cpu liquid cooling block.
Click to expand...

I think it's pretty obvious from that picture that anything that hangs over the edge of the CPU socket (like the tuniq) is going to be incompatible with the HR-05. Big.Wayne has had excellent results with the Thermalright Ultra-120 which has the added benefit that you can use any fan you like and the orientation is less important than with the tuniq.
 
So do you reckon the hr-05 will fit if i use TR ultra 120? I've seen big.waynes thread but wasn't sure if there was enough room for the the hr-05. ty for the reply btw
 
Cheers, guess I'll order 120 ultra and slap a fan on it, ty for the advice.

yeah arctic 7 pro is a lot smaller than tuniq or 120 ultra, one of my mates got one, seemed fine when he first installed it but now its a bit loud and high settings and I'm no too impressed with it's performance.
