I just brought 4ghz bundles with new Antec 1200 Twelve Hundred Ultimate Gaming Case because I took it back to overclockers as Rich had sorted out my cpu cooler not seated correct and temp went too high over 90C+ as he advise me to get a good airflow tower case as this is the main reason I had brought a new Antec 1200 Twelve Hundred Ultimate Gaming Case to fitted the motherboard on it.

I got serious problem now with my parts here:

Antec 1200 Twelve Hundred Ultimate Gaming Case
Core i7 920 D0 4.00Ghz
Patriot Viper 6GB 1600Mhz at 8.8.8.24
Titan TTC CPU Cooler Fenrir
Arctic Silver 5 Paste (Rich had sorted it out for me)
Gigabyte GA EX58-UD5
Corsair toughpower 750W pwer supply
Geforce 260GTX x 1 (at freq 101)
DVD-RW Writer x 1
Samsung spinpoint F1 7200RPM 1TB Hard Disk x 1

The pc run at idle at 54C 4.00Ghz but full load at prime95 after 5 minutes the temp was reading at real temp 3.00 is 96C (too high)

Run flight simulator X and load the game, after 2 minutes the pc freeze and stopped but temp reading at 81C with around 25% in use. Graphic card temp is 47C.

I turn off 4.00Ghz and go back to 2.66Ghz and flight simulator X with temp at full load was normal under 70C after 30 minutes using prime95.

I don't know why is not stable and why is temp run over 90C+ with full load as couldn't playing flight simulator at 4.00Ghz ?

I thought the tower case is great airflow as all cable management cables, wires was hidden in the back side of the case leave all motherboard very clearly and space for a good airflow.

What can I do next ? I was disappointed as I thought Rich advise me correct of buying the good tower case with good airflow but compare to my old tower case, it still the same, no different to flight simulator x freeze and temp went too high.

Very disappointed and really annoying. Spend £540 on the bundles and spend £138 on the new tower case.

I kicked myself of wish not purchase it all in the first place and just forget the 4Ghz bundles.
 
Not sure whats going on with these 4Ghz but its nothing to do with antec 1200. My room is small and pokey my room temp is 28c+ on night so warm. 3 front fans on lowest settings 2 rears on Med and top on low. 2 hours 15 min prime 95 @ 4.00Ghz Peaks at 71C can suppy a screenie if you like. If i had to guess and thats all it is i would say these fenrir and not the bess kness people expect. People also said the nero was really good when they were in the bundle...;)
 
70 degrees at stock 2.66 sounds rather high to me, but then again 32 degrees in your room, my computer lives in a rather more modest 24-25 degrees room (summer temp).

Some chips just dont overclock well, if your coolers on well, and its gained over 20 degrees from the overclock, I would imagine its just not the best chip.. but thats gotta be in your favour as you bought it as part of a guaranteed overclocked bundle.

To me 32 degrees isnt "only" its uncomfortably hot, and imho far to hot for "seriously" overclocked systems.

Don't know if the antec's fans are speed controllable, but you'll want them all running flat out, as your certainly running with a "handicap" with the room temperature so high. Ideal ambient temperatures for a PC (or stereo, or TV.....) are 18-22C, above 26C it gets much harder to keep them running cool.

I am seriously re-consider take it back to overclockers to get rich to test it out again ? Cos I know it not right at all. Or maybe I can buy V8 Coolermaster cooler or go for Noctua NH-U12P SE1366 CPU Cooler with two fans together or go for Akasa AK-967 Nero Direct Contact Heatpipe CPU Cooler or even better Thermalright Ultra-120 Extreme CPU Cooler with two fans ?
 
Get OC to test it in their air conditioned workshops, if the temperatures are good while in a properly regulated environment, but are 90+ when your at home, then you will have to resort to more powerfull cooling, If you want a good cooler, look for one which allows a fan on each side of the cooler in a push/pull config. Dont just bolt two fans together on the same side, as its less efficient imho.

If you cant get the ambient temperature down, your going to need extreme cooling.

On the other hand, if your chip is reaching the high 80's in OCUK's workshop I would complain that it really shouldnt go above 75 or so, more like BigBruiser's setup.

Good luck
 
I belive i read somewhere on here the all the ocuk 4.0 bundles are tested in a carboard box to simulate poor airflow, which is good if true as almost all cases will perform better then that. but it seems evey day there another problem with recent bundles....maybe there just selling to many:p
 
I had phoned up Intel about DO stepping cpu processor overclocked and phoned up Gigabyte about the board overclocked.

Intel told me that the i7 920 D0 stepping cpu processor is not advise to do overclocked of more than 3.20Ghz and the cpu temp should be no more than 67C for 3.20Ghz overclocked. They also told me if I use 4.00Ghz overclocked and temp of no more than 80C but the lifespan will be reduced and no guarantee for the cpu to die at anytime. They advise me to stick with 3.20Ghz no more than 67C temp. They advise me not to do 4.00Ghz overclocked.

The gigabyte told me that my board can cope with overclocked but only up to 3.20Ghz support for my GA EX-58 UD5 but were suggest me to go for the top range motherboard GA EX-58 Extreme with water-cooling and should be stable at 4.00Ghz+ overclocked.

So, I had to go back to 3.20Ghz default and that's it. I don't want my i7 920 cpu processor chip going to die if overclocked 4.00Ghz and over 67C in temp. Not worth to lose my cost money on the cpu processor and motherboard.

I think overclockers co uk should sell i7 920 with water-cooling with gigabyte extreme motherboard instead ?
 
i have magic beans for sale too mate intreasted (j/k). Dont belive everything you hear. The life of the cpu will prob decrease at 4.0Ghz but were talking it will last 8 years instead 18 if you see what i mean :p
 
When I overclock my i7 920 I'm just going to find whatever clock speed gives me ~70 degrees under load and leave it there. That is easily within the CPU's temperature limits and also leaves headroom for unusually hot days.

Intel telling you to not go above 3.20GHz is just them covering their arses. What would happen if they told you 4GHz was fine, you went to that level, and the chip died? Exactly.
 
I agree with others that the cause of this will most likely be your ambient temps. 32 degrees is way too high for ambient, there's no wonder your chip is overheating! IMO at that kind of room temp you will need water cooling to achieve a stable OC that high.

Airflow through the case will of course help, so Rich was absolutely right to advise that, but did you tell him what your ambient temp was? If you can knock 10 degrees off your ambient I bet you'll find the rig is stable at 4GHz.
 
Atleast your system is stable!!!!!!!!!

Mine wouldnt turn on when I recieved it? After clearing the CMOS and loading a different BIOS setting (there were 3), it booted at 4ghz. Just come back from gym and it's obviously crashed and cant boot anymore. Keeps powering on/off!!! Sitting now at 2.66ghz.

I run mine in a room with a aircon that keeps the room at about 20c.

Not happy at all with it......
 
as stated before

if you have issues with your bundle - post in the RMA and tech section of the customer support forums so that i can help you out
 
With respect, Intel, and the motherboard makers are naturally going to recommend against high overclocks, and try and get you to buy the higher models.

Doesnt mean that the 920 wont do 4ghz for many years without problems though. As for the warrenty, you should have at least 12months direct with OcUK, Perhaps longer, ask OcUK what their procedure is :)... Probably depends if the bundle includes a retail processor or an oem one.

The advise on watercooling has some logic, based on the temperature of your room, which frankly is too hot for a high power computer, on air cooling. (Unless you install massivly powerfull high airflow fans to keep everything cool.) Your' also risking your hard drives, which are pretty sensitive to overheating.

Yeah agree with the above small box rooms are simply put nightmares ive always had to live with silly high temps even my Q6600s ive had like 6 of them all gos and some non gos always hit 60c+ idle.... and thats with monster coolers even the thermalright ultra.

Even my Q9550 is on a sunbeam cooler and hits 58-60c idle with all doors/windows open but room temp is 30c atm.

Only thing as suggested maybe a better cooler like the Prolimatech Megahalems or better.

Im not too fussed tbh atm theres sod all games/apps that even need the power of a Q6600 so for now im staying clear of these 4ghz bundles....
 
I had finally sorted it out myself. I had brought myself a new infrared thermometer to test the ambient temp is 22C. I had also replaced the new cpu cooler - putting the new V8 Coolmaster and dumped the Titan Fenrir and guess what !!!

Idle temp of cpu is 42C (4.00Ghz) V8 Coolmaster
Idle temp of cpu is 54C (4.00Ghz) Titan Fenrir
Full load of cpu is 77C (4.00Ghz) V8 Coolmaster (full load for 60 minutes)
Full load of cpu is 96C (4.00Ghz) Titan Fenrir (full load for 5 minutes)

It now stable when running flight simulator X after 60 minutes playing the game with V8 Coolmaster and the cpu temperature at around between 42C and 77C for 60 minutes without no freeze !

So, the V8 Coolmaster had now resolved better than rubbish Titan Fenrir.

I am happy now. Much relief myself. It a pity that Rich never try out the V8 Coolmaster on the bundles.
 
The Fenrir when installed correctly is more than up to the needs of the 4.00GHz bundle as has been proven hundreds of times over. :)

Are you sure the Fenrir was seated correctly with good thermal contact?
 
Perhaps ocuk may have solved some of the issues maybe it can be shipped with the heatsink attached correctly ? :)

That way if the bundles tested in a cardbox/worst case prime scenario then at least theres no room for error once it reaches the customers side.... only the Case/p/s are the only other culprits in case of issues.
