Sandy Bridge under Phase @ 5Ghz....

[eOn]

Well I have now had my Mach 2 GT upgraded by Little Devil and am planning my next upgrade...

I have been out of Overclocking for some years and am now trying (hard) to catch up with what's new. And wow has OC changed over the last 3 years.

So I'm looking at a i7 - 2600k and a P67 Sabertooth to add to my modded Mach 2, however I'm getting some conflicting reports that sandy bridge does not like minus temps? Is there a cold bug? Will I be better off with an extreme non-sandy bridge chip? I note some benchers getting near 5 ghz on air!??

Can anyone recommend the P67 board? I want to set a budget of about £500 for the chip, motherboard and memory so that rules out a Maximus IV or an extreme chip. (If it's the only way then I wil have to wait and save some more pennies).

I'm aiming for 5Ghz with SLI (I have to 460s) 24/7 stable.

Your advice would be most welcome as there is so much info out there its all a bit confusing!

I am using Asus Maximus IV Extreme - 2600K - gskills 17000 and I run all benches at 5600mhz with no problem. Memory runs 2300 @ 8-9-8-22-1 with no sweat. And of course this is on phase. Your Mach II should work a charm.

Just re-read my post and wow typo is me.com..... Sorry about that, will now edit.

Thank you for your reply, I really appreciative it. Obviously your board is a top end P67, does anyone have experience with the sabertooth (as its half the price)? Could I have your settings for the 5.6 clock? I would be very happy with a 5.6 over my current 4 on my (now quite old) q6600........

My goal was to let you know that Sandy bridge did like cold to a certain point. Obviously your purchase of HDW will fit your budget. Asus has several good boards along with Gigabyte and a few others. I think you can get some great overclocking gskills at a modest price. You will need 2600K to get 5.6. Most 2600K are running 5.2 to 5.3. There are several for sale in the classifieds.
No need to post settings until you get a board.

I can move this thread to Intel if you like. JLMK

[eOn]

Yes please, thank you.

How do I get access to the classifieds?

[n00b 0f l337]

100 posts and some time to get access, so keep contributing

[eOn]

LOL so 5 years isn't enough..........

(Must bench more)........

[n00b 0f l337]

Give an admin a PM if you think your situation is different, I'm not sure I know any exceptions, but 5 years is quite a bit

[eOn]

Thanks for the heads up. Sadly I need the 100 posts thing before I can access the sales area, so if anyone is looking to sell a good clocking i7 - 2600k let me know please. Other than that, has anyone had experience with the ASUS Sabertooth boards?

Thanks.

You should be able to do 5Ghz on air unless you are unlucky with the chip you get. At 5Ghz sub zero isnt going to do anything for you and it would be a waste to bother with it. For sandy bridge sub zero only benefits the top end where you are using a lot of voltage (~1.6v) as it eliminates instability from high temps.

[sin0822]

yea its more like SB doesn't like the cold of LN2, DICE and phase seem to be working charms.

[Leeghoofd]

You just indeed need a good chip that ca do 5ghz air... 24/7 SB under cold isn't required... Sabretooth gives me 100mhz less in OC... compared to Pro or Dlx boards... but to find that good 5ghz air chip can be a pain...

Think he isn't interested in benching but is more looking for a 24/7 system... for benching (5.6-5.7) I use LN2 and keep temps under control, most 5.7 chips we have in the team are -5 to -20 lovers, colder temps usually results in crashes in Pi32m and co

Whoa! That's most interesting. 5.6-5.7 with sub zero must be the "realistic" max for SB then. (I have an SS to hand for use on my SB and was wondering what a real world max was).

Sorry, don't mean to hijack.

[eOn]

You are quite correct I am after a stable 5Ghz machine. I already have the SS phase so what I'm trying to figure out is which motherboard and CPU to get. So far I have settled on a i7-2600k but now I'm trying to decide which motherboard to go for. I think that I may be better of spending the £ and getting the Maximus IV. I really want my OC to be stable.

I did notice that many are getting 5Ghz on air and did think that maybe SS phase was an overkill (to get a few extra hz) but hey isn't OC all about getting the maximum hz you can get??

I am a bit confused about which motherboard does what over the other. For example, the x58 has tri-sli? And the 1155 boards don't? What I would like is tri-sli, ide (my dvd burner is still ide, does any new board support these still?), mega stable OC, RAID and if possible a board that has space around the CPU for my phase cooler to fit.

So, ASUS or Gigabyte? Which will give me the biggest OC and all the options I would like??

Phew, hope that makes some kind of sense. Thanks again for your help in advance.

Tom.

[Eldonko]

Pretty much nothing has ide anymore. You can buy a sata to ide converter but it is cheaper to just buy a new dvd drive for $20.

ASUS and GB both have plenty of good 1155 boards. What board you want depends on if you want SLI or not. If SLI is important and you may even add a 3rd card you want a board with a NF200 chip. If not then you can save the $$ and go with a UD4 or Pro.

im awaiting my ss with mive

[eOn]

Yes I think I do want Tri SLi (I'll have to sell my 460s), maybe in a year or two. But what I really wnat to know is does spending £300 on a board really mean that's the best way to get a higher clock? Or for £160 will I get 90% of the same?

Truth be told I think its looking more and more like a Maximus...

[Mysterfix]

Don't waist your money on an extra expensive board. Any mid to upper lvl board will do the job, just go with the board that has the extra options you want or need.

[eOn]

Well after much thought (and some buying and sending back) I ended up with a i5 750. Why do you ask? Well I ended up being offered one at a very good price so I sent back the SB motherboard I got and plugged this baby in.

So far after minimal testing I have already hit 4.7Ghz. Not got it 100 stable yet but I'm only at 1.4 volts.... So I'll let you know how I do and may submit this to the LinX table?

Tom.

[skuldarin]

with a 750 you'll probably need to go chilled LC or phased if you want 5ghz stable. 2nd gen 32nm chips like sandys have alot easier time hitting though high notes without much worry about cooling than the rest.

[eOn]

Yep I can see that. I did this because I have a phase unit and decided that rather than spend the £600 to get SB, I'd live with this much cheaper solution. Currently LinX stable at 4.5ghz, just having issues getting the system to run LinX at 4.725. Odd as it boots into windows and runs most other things at 4.725 but my goal is to get LinX to run stable.

[jcniest5]

If my memory serves me correctly, the Sabertooth has a LN2 mode (via a switch on board) for those extreme cold boot, which should ease your mind if you plan on using such cooling system.

[Dumo]

Odd as it boots into windows and runs most other things at 4.725 but my goal is to get LinX to run stable.

Do you want to stress test your cpu or your phase cooler?

Probly your cpu can handle that test, but your phase cooler can't handle the load.

[eOn]

lol my phase is modded by little devil, trust me it can handle the cpu. No its something else. I have just got got it stable at 4.5 but I can see in cpuz that the multi is changing by it self? Odd as I have turned off all the self clocking stuff? Anyone else had this?

[st0ned]

Disable speed stepp and C states @ Bios


Else you have a Mach2, unless it has a new evap, new condenser and a new compressor, proper gas etc ( where's the mach 2 ) It might ( or not ) to handle proper loads, no matter who mod it. It's all limited to original mach 2 stuff.
