What's your chosen mobo? I'd make sure to get a 2 oz copper PCB board for the Silver Arrow. I think Luca is right about using low voltage ram. Otherwise it looks like a sweet build.

EDIT:Saw you were going with Asus Maximus IV now. Probably the best choice for what you want.

The only disadvantage I see for the P280 over Define R3 are the open top vents. Fractal include their ModuVents: http://www.tweak.dk/images/2010/review/1141/tweak_dk_fractal_design_refiner2_27.JPG Anyone have an idea how one would hack together something similar? EDIT: Should be in by mid-December i...

Argh, wish Antec released this before my SB upgrade. Looks sweet.

If prices are any cheaper and you wont use dual SLI consider Gigbayte UD4 to be a solid alternative to Asus for the mobo.

I have the 3TB WD GP and its not whisper quiet like my 1.5TB(same acoustics as the 2TB). Right now the 2TB WD GP and Hitachi 5K3000 2TB are the only large capacity drives that are up to SPCR standards.

Already jonesing for Noctua C14 though. Noctua C14, well maybe. The hot ticket right now seems to be the Thermalright HR-02 Macho, which my local dealer has for about two-thirds of the price of the C14. Yeah, it's not value champ. I used a TR SI-120 for my s478 and s775 systems so I might be a bit ...

For your consideration, Asus and Gigabyte use 2oz copper PCB compared to standard 1oz which is good news for those nice heatsinks that approach 1 kilogram. Gigabyte uses cooler running Driver-Mosfets for for the voltage regulator circuit. Might bring some small advantage in a standard ATX case with ...

Turns out only C1E and higher C states caused the chirping noises. SpeedStep/EIST can still be active for an excellent power consumption reduction at light loads. I achieved this by disbling C-states in BIOS and running ThrottleStop with the following options:

Sorry guys turns out it's normal for Prime95 in-place mode to vary the temperature, the same applies for Blend mode. IntelBurnTest(same as LinX basicaly) really heats up the processor, reaching 78C max in standard mode with the stock cooler at (constant)1200rpm and a Nexus 120mm at 700rpm for side i...

I think that you have just to do what HFat already suggested (providing that I have well understood him): disable any fan control and run the fans at 100%, disable any power saving feature in BIOS, then run your tests. Use the specific OCCT PSU test in order to check voltage stability (see the resu...

I could see the concern for temp readings accuracy for a previous generation processor, but for Sandy Bridge? Or could the board be messing those up? I don't have suitable equipment to measure the heatsink temps.

Didn't except different result but I have one less thing to rule out with certainty now. Klusu, What could we learn by measuring HS temp and power draw? On a diffident note, could the PSU have a part in the temp rise by feeding off-voltages to the board? EDIT: Damn, wish I payed attention this graph...

Okay I connected the fan header to a PSU molex connector via an adaptor. Same results.

It's been connected to the 3-pin header since day one, I discovered the fan could spin at ~800rpm minimum compared to ~1000rpm minimum from the 4-pin header. It stays at constant ~1500rpm IIRC after a few minutes of Prime95. Nevertheless I'll see if anything changes when my True Rev. C arrives and h...

Nevermind

You know, the more I look at your graphs, the more I think the PWM settings are wonky. The Prime95 graphs show the temperature spiking, then drooping. Mine do NOT do that, and I've never seen that on any of my machines, ever. P95 always causes that curving ramp up until it hits a zone of a few degr...

The stock cooler is adequate but that's it. The fan has an irregular tonal quality even when spinned down so I'd recommend replacing it, personally.

When run with default settings, most variants of Prime95 (eg, OCCT) alternate between small and large FFTs. Small FFTs generally fit in the CPU cache and run hotter. Large FFTs thrash the cache, so the CPU cores spend more time waiting on memory fetches. What specific Asrock board do you have? Do y...

I wish!

Just for fun, what heatsink and CPU fan are you using? Why the same one Anandtech used to overclock a 2500k to 4.5GHz, Intel stock cooler. :wink: That said I'm avaiting delivery of a Thermalright True Rev. C. Theres a setting in UEFI called 'power saving mode' that applies a conservative undervolt ...

Ran another Prime95 sesson and kept an eye on the multiplier in Realtemp as well as Intels monitoring utility suggested by lodestar. Stays at x34 throughout. Baseclock stays at a stable 99.78MHz after a minute or two of Prime95. As expected, sadly (would have been a pleasant surprise if not).

TurboBoost kicking in ? It kicks in if a certain performace/heat is right, right ? Someone should slap you guys for not knowing how TurboBoost operates. :P Turboboost doesn't apply here as all cores are fully loaded. Here are the results of my testing: http://i.imgur.com/hZ9m0.png Graph starts with...

I recently built a Sandy bridge system for my self, details in my signature. I'm getting an unexplainable sudden tempurature rise after runnuing Prime95 for approx 17-18 mins: http://imgur.com/RiBBc.png If I stop Prime95 and run it again the CPU tempuratures drop down to normal: http://imgur.com/Pxp...

I still have the old Sonata I which came with stiffer black rubber grommets. AFAICT The Sonata III came with the same white soft rubber grommets and longer screws like the Solo/P150 but otherwise unchanged trays. If you have Sonata I/II trays Antec has the newer white grommets as a separate part. Wi...

Today I re-arranged my room and found the hard drives more audible than before. It's a type of constant low frequency noise as well as a low thud during seeks. If you read the review by Lawrence Lee he hints at the HDD trays having a resemblance to Antec side mounted trays. I discovered it was not o...

Good to know. I'll give the push-pull config a try and report back. As you can see from my sig. I've already indulged in some OC'ing, mostly for fun though. At stock my apps run so much faster than before. Certainly has been a worthwhile upgrade so far performance-wise. Very content with the on-chip...

http://i.imgur.com/xxA9i.jpg So here we are now. The Z68 SSD cahing didnt turn out to be applicable for me. I'm rather impressed by i5 onboard graphics though, video neither tears or jekrs, some flash video streams looks higher quality than they did in the 9800GT. Haven't gotten to OC-ing yet. Stil...

I was plagued by the same chirpy cricketey noise. I had to play with C1E, Speedstep and Thermal Monitor settings in BIOS to get rid of it on my VX450. Yours seems awful loud though but maybe the microphone is more sensitive to high frequencies. If the BIOS settings doesnt help consider an RMA, Corsi...
