TPU's Core i7 Overclocking and Feedback

[Thrackan]

Just saying from what I saw, for some reason java based programs always run slower than C++, and use more memory.

The old saying "Java = slow" doesn't have to be true with today's development environments. The truth behind that saying usually involved Spring-based programs and while Spring is still being used, it has lost a fair share of ground in the Java world.

Still I can imagine a slight setback from using the runtime environment, but not as much as Spring did.

Finally!

This makes my Q9400 on my old P5Q Pro feel soooooo slow. I initally had it down to .950 vCore (~.925 Windows) and 1.2 vQPI in TurboV with OCCT running, but I realized that I was on the looser 9-9-9-24 1T. I switched over to the XMP profile and ran this all last night.

grats on your low voltage stock clock.

 

[mastrdrver]

I got it off ebay and was pretty sure that it was a 3849b028 batch. Got it thinking I might have a good chance to get a decent clock out of it without going nuts on the voltage. When it arrived, it ended up being a 3903a468. Check the ebay link again and no pic so I must have clicked on the wrong one. Either way, I was just happy to have one since I got my board and memory back in March on a Newegg shell shocker deal. Was going to wait for 1156, but couldn't pass up the deal.

When I got it all setup and only flashed the bios to see D0s, I booted into Win 7 and ran Vantage to see if when I would get. Best I ever got with my Q9400 at 3.4ghz was just over 14k. Stock clock 920 and memory set to 1333 and the timings listed above, I got ~15,500.

Needless to say, this low voltage just makes it that much better. Now I just need to reseat the OCZ since I just wanted the new system up and did a so-so job of seating the cooler.

These are miles easier to overclock than any Core 2 chip. No messing around with settings I don't fully understand and guessing at others. Its just too easy. I feel like I'm missing out on some hidden mystery I don't understand.

 

[mastrdrver]

Is there anytime that the X58 voltage would need to be upped? Also, does anyone know what default cpu voltage amplitude is? Asus just gives auto and then goes from 700-1000mv.

 

[Binge]

There are times. You should take a look at the x58 chipset flowchart. It really makes sense once you get an idea of what each chip controls and how that works with the CPU. You can google images x58 chipset flowchart and it should come up with some results.

Need a bit of advice guys please, looking to get all the parts for an i7 rig in the next couple of months. I'll be getting an i7 Do and looking for the best motherboard to overclock it up to 4ghz. Ideally looking for a board that offers solid performance with no overheating problems and no strange quirks. This will be on air and also looking to crossfire a couple of hd 4890s. Any suggestions please.

 

[Thrackan]

X58 chipset = X58 chipset.
Basic advice: Look for a board in a price range you like and check if the chipset cooling is well.
Crossfire is possible on every board with more than one PCI-E slot, solid performance is mainly based on the proc and the chipset.
As far as the rest is concerned, check the features you need (raid, sata ports, onboard sound or whatever).

But if I have to give you more specific advice: I am very much satisfied with my Gigabyte UD5
If you're looking to OC, tons of BIOS options there too.

And yet some boards overclock better

And yet some boards overclock better

4Ghz is possible on all boards, depends on the chip whether you make it or not.

Some boards handle their power better, true, but we've all seen Fits going crazy on a cheapass ECS board too. Read back in this thread if you missed it.

Either way, unless you tend to shit money daily, I suggest to stick with a normal budget since "high-end" boards like the EVGA Classified add near nothing but are still double the price of a "mid-end" board.

+1 ... it's the best board I've had in ages and if you're only looking to get to 4GHz.. you'll get there easily with a good cooler.. no problems!

Gigabyte is pure pwnage

 

[mudkip]

I'm currently overclocking my grandma's P4 Northwood 2,6Ghz , It's running 3Ghz (13x231) @ 1.625v) now without any trouble at all haha. Full load 62 degrees.

Mobo: P4p800
Ram: 1GB PC3200
GPU : Geforce ti4400

Got a better seat on my V2 and now I got 40(x2) and 36(x2) which is better than the 10C delta I had from core 0 to core 4. This with 1.15 vCore in Bios as before I had similar temps with 1.0 vCore. In did some looking around and does everyone show about a 4C difference between the 2 hottest and 2 coolest cores? I thought it was my V2 until I reseated it. I still have the difference and noticed over the last 2 days that others had it too.

As T_ski requested......Got it to 4.0Ghz but temps are crazy.....Will have to get a better radiator with more volume (I remember Binge). Here she is @ 3.8GHz which is my goal for a 24/7 folder/cruncher.

[t_ski]

bogmali, start taking your vcore down a step at a time until it loses stability, then up it back up one and do longer stability tests. Then do the same with other voltages. This should help with your heat, as not all 920's, T-Powers, etc. are created equal.

Right you are, right you are!

You know, as soon as I saw you post I was ready to start dodging something that comes through my PM from you I'm glad you're having a very good day and thanks for the inputs

I will do just that......The wifey has something pressing for me to do so you know cause it's my day off Will have to wait 'till later tonight.

Hi all just about to order i7 920. Should I be asking for a D0 do they o/c better? I have built an i7 rig for my parents but never O/C with it. From memory looking @ the bios I think I may need some guidance getting a nice stable 4GHz out of it. Totaly different setup to what I am used to playing around with.

Edit: buying new should get me a D0 now anyways

 

[Baer]

There have been some on sale the last few weeks that are still C O so I would ask.

 

[n-ster]

SLBEJ I think... is what you look for that on your box for a D0, and yes D0s TEND to be better... Most D0's are equal or better than C0's nowadays, even though early D0's weren't that great
