Hello, I have a few scenarios set up so when my cpu arrives in a few days, I will be able to dig in =]. Just need some confirmation/advice.

I am running 1600MHz memory and I have a CCF CPU cooler.
I would like to oc it in these steps til I find what I'm looking for. I've heard from a few sources odd multipliers are this chips favorite, not sure why or if it's true, but I made these accordingly...

Which settings Auto adjust along with BLCK? Most of them? All of them?
Either way, it will be nice to know numbers for checking if it's running correctly.
I have no idea what the voltages will be exactly, but i'll just tinker with it unless people have suggestions.
Let me know if this looks right or how you would improve, first time OC'ing without unlocked multiplier :(  :

3.04 GHz

BCLK: 160 x 19
DRAM: 160 x 10 = 1600MHz
UCLK: 160 x 20 = 3200MHz
QPI: 160 x 18 = 2880MHz

3.36 GHz

BLCK:160 x 21
DRAM: 160 x 10 = 1600MHz
UCLK: 160 x 20 = 3200MHz
QPI: 160 x 18 = 3600MHz

3.8 GHz

BCLK: 200 x 19
DRAM: 200 x 8 = 1600MHz
UCLK: 200 x 16 = 3200MHz
QPI: 200 x 18 = 3600MHz

4.2 GHz

BLCK: 200 x 21
DRAM: 200 x 8 = 1600MHz
UCLK: 200 x 16 = 3200MHz
QPI: 200 x 18 = 3600MHz

Thanks :wahoo:

I have got Core I7 920 DO, I have o/c at 3.4 ghz.

BCLK : 170
DRAM : 850 --> 1700 MHZ
Timing : 7-7-7-24
Voltage DRAM : 1.64V
UCLK : 3400 MHZ
Coef : X20
Voltage CPU : 1.16V

I didn't try over 3.4 ghz because it heater even with Noctua NH-U9B

You must adjust CPU VCore, DRAM Voltage ( 1.65V max limit), CPU PLL (1.8V), QPI/VTT voltage (1.2V) this is my custom's.
Temps max : 33° iddle and 52° burn

Thanks clement, although, your max is only 52... not planning on going any higher?

Voltage's will be a big help. =]

No, I isn't planning on going any higher because I needn't so much powerful ;)

Voltages posted are my voltage's, I just fixed minimum voltage becauce I don't like use the Auto voltage setting when I o/c

That's a pretty damn good voltage for your OC isnt it? .. Of course, it looks good to me because I am running a X3 720BE 2.8GHz @ X4 3.4GHz... it needs 1.45v, so i'm excited to install this thing. =]

More performance, less power? Yes please.

Yes it is. You'll tell me about your o/c CPU, The last Core I7 D0 released is pretty cool, more o/c with less voltages compared to previous Core I7 (C0) which were released on november 2008.

More Performance, less power Yeah !! that is cool but even though I fixed a low voltage (1.16V), this cpu gives out a lot of heat because of HT but it useful if the software was optimized with it

Yeah, I'll let you know how it goes. It was supposed to be here today, but it's gonna be late. Tomorrow morning. I'm pretty sure all 930's are D0, no? :D

So, 1.64 is the Max recommended DRAM v? Do you have overclocked 1600MHz modules?
Did you edit QPI/DRAM Core Voltages at all? (about 1.2-1.4?)

No I haven't o/c my modules. My modules are G.Skill Trident PC16000 9-9-9-24 3*1 GB. I just downclocked it but I have also decreased timings to 7-7-7-24. I don't know which is better (Frequency or Timing)

1.65V is the max Voltage recommended by Intel but on asus motherboard you can increase the memory voltage of 0.2V step by step so you can fix 1.64 or 1.66 but not 1.65V

Yes all core I7 are D0 of course ^^
What Motherboard and Modules did you buy ?

Thanks for the pic.
As far as timing vs. frequency, I'm not sure either... I've read articles saying completely different things, so I guess it's preference.

I'm getting multiple GPU's so I got an EVGA E758-A1
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
And, I'm just using my older modules, I'm no memory expert, but I think it will get the job done: 8(4 x 2)GB OCZ Obsidian 1600... I have them set at 8-8-8-21.

Nice, EVGA is ****** great brand, I didn't know this MB modele. OCZ is also a good memory brand. On the other hand, if you want to o/c what cooler will you use ? because a Core I7 gives out a lot of heat. ;)

Haha Yeah I'm looking forward to EVGA's support and warranties.
I have a Sunbeam Core Contact Freezer on the way also =] so that's covered.
Well I would think so, the cooler got great reviews, especially for the price... I just had to get a bracket set for 1366 compatibility.

My finished rig will be:

Core i7 930
EVGA E758-A1
8GB OCZ Obsidian 1600 8-8-8-21
Sunbeam CCF
80GB Intel X-25M & 500GB Caviar Blue
SLI GTX 480's
Antec Twelve-Hundred Case
Antec 1200w PSU

8D (Overkill on the GPU's, I know, but I'm playing at high resolution and I want this beast to LAST)

I think I will stick with whatever OC i can get out of maybe 60C at full load, the 480's are already power hogs and hot too. Case should allow great airflow though.

Hey,

I think that 8GB would not be appropriate for your setup as the i7-9xx line of processors utilise triple-channel memory, which means that you can only go in multipliers of 3 (3GB, 6GB, 12GB, 24GB and 48GB).

I'm not so sure if 8GB would work, so confirm this with someone else before making your desicion.

EDIT: Woops, didn't realise that you have already bought the RAM. I'd personally prefer Corsair RAM over OCZ as they usually have compatibility issues. I am not definitely sure if 8GB can work or not so leave it to someone more experienced or try it yourself.

OMG ^^ SLI GTX480, I'm ATi fanboy lol, I just prefer Ati compared to nvidia because nvidia is too expansive for me and have the same performance in game but nvidia fermi just have some problem like the noise (losing my hearing during a game^^), the consumption (maybe Nuclear power plant needed) and the dissipation (I'll be able to heat my home).

I jocked, yes it's BLAH... but I don't want to troll. The GTX480 is a good card with good performance but it also has imperfection like HD 2900 XT

Thanks a ton, I think you're right... So I'll be limited to 6GB (3 x 2GB) of memory unless I grabbed some larger capacity modules. Do you think that 6 GB of memory will bottleneck anything in stressful situations? I wouldn't think so, but I'm selling my current system to my gf and was planning on keeping the ram.

I don't PREFER ocz either, but that's what I already have had for the past 2 years. No sense getting new modules when these have served me well, unless performance will be hindered.

Haha, well it is a lot of money first off, although the performance of SLI 480's is worth it to me, in-game performance is def not the same. Especially since they're overclocking maniacs. The noise also, is not an issue for me (although I hear the noise is exaggerated and isn't AS bad as people say), When the GPU's will be at full load, I'll have headphones on for games. And the heat, also not really an issue, I have tons of fans and a large case with good airflow. It will limit overclocks, but a big OC won't be needed anyways.

Now, I don't o/c my GPU anymore because I broke 2 GPU, My HIS X1950 XT 256 mo and sapphire HD 3850 256 mo, my screen shut down during any games, so now the O/C GPU is gone for me.

It's useless o/c GTX480, it's already powerful anyways, I think you won't be needed.

Granted, it's kinda useless now, but in the future it will be a big help for new games. Apparently if you have good cooling, it's a monster.

Here's a water block review, I don't have water cooling, but it shows how much potential there is:

Nope, the RAM won't be bottlenecking your Graphics card. 6GB would be enough, I would also recommend the i7-920 over the 930 because of it's cheaper price and overclocking capabilities if you get the D0 version.

Your PSU is just good enough to power the power-hungry GTX480, and I hope you have enough fans to keep the temperatures down. Overall a good system.

Alright thanks, yeah It seems 6GB is working fine.
I'm pretty sure 930's are all D0 stepping, and I got the CPU for 199.99 so price wasn't even an issue.

The 920s overclock better thant most 930s because the 920 holds more better batches while the 930 is relatively new and has less. After time the number of batches for the 930 would increase and you can get a better Overclocking 930.

Here's the system all set up, These max and min temps are from idle and running Kombustor.
Stock settings, 80% Fan on GPU's.



EDIT: I can't get a completely stable overclock, and it's because of my memory I think. If I set the timings to what they were on my old system, I blue screen. If I set them to auto or looser timings and freq, it runs perfectly...

I used to run at 1600MHz 8-8-8-21
Now it wont even let me run at 1600MHz 9-9-9-24, or even 1600MHz for that matter. =/ Confused...
