The 1055T makes it a little more interesting.

[theoldtimer]

I’m about done testing the 1055 under the chilled water. I kinda want to run a few tests using dice to see if the colder temp will give a little more HTT clock at the x14 multi? If I don’t kill the 1055 I’m going to build a gaming rig around it.
I already have a new Cooler Master HAF932 case sitting here waiting. I’m working on a good water cooling system for the case in the mean time until I can get a good cool dry day to test the 1055 under dice.

I probably should do a complete fresh OS install and reflash the bios before the dice tests as they both are trashed.

At the x10 multi the HTT maxed out about the same for both the 1055 and 1090’s.

Anyway here are a few of the 1055T tests I’ve ran so far. I ran some at the x14 multi with the HTT between 328-335 but I’ll post those up later.

System spec.
1055T ASUS CH4F bios 801
4GB Corsair GT 2000 CL8
Asus 5970, or 5970+5870 or 5970+2x5870's
windows 7 64-bit
chilled water CPU cooling

[theoldtimer]

I tried the x14 multi on these tests but the cooling fluid was getting warm by the time I got around to running them.

I ran into a couple of problems with 3DMark 03 and 06. 03 wouldn’t start when running high HTT for some reason maybe a fresh OS and driver install will fix it? 06 had problems with the cat drivers stopping and when I did get it to run adding the two 5870’s only yielded another 600 point +/- over the single 5970. Vantage unlike 3DMark06 works well with the cat drivers and I can over clock the GFX cards without a problem.

3D06 4xGPU's but the other two GPU's didn't help the score much.

I've had a daiquiri, so forgive me, but HOLY ****!

407 FSB! WOW!

Btw, why does it show 3.73 ghz highlighted when cpuz shows 4ghz?

[Daveburt714]

Impressive OT!

There goes my conspiracy theory....

I even switched back to 0801 last night and still have the same HTRef limit ~300.
It's either the cold, or I've got a bum piece of hardware (board or chip).
I've got a C3 965 sitting here, If I get a hair this weekend I'll swap it out and try again.

GJ and thanks for the screenies...

hey man, nice htt!!
Here a picture, you have 6 sec. on wprime...

I’m not sure where you’re seeing 3.73GHz so please indicate its location in the SS. One thing I did notice is that wPrime shows the 1055T as an engineering sample but in fact it’s a $199 retail chip.

Here is a wPrime-1024 @404HTT I didn’t get to try it @407HTT so I don’t know if it would finish wPrime 1024 at the higher HTT clocks?

Thanks Dave, it’s probably the cold helping the HTT clocks but I’ll know when I test it under ambient water inside the case after I build the gaming rig. I think I’ll flash the 905 bios today then test HTT with it. I think while I’m at it I’ll try my old Corsair CL9’s too to see if they kill the HTT clocks?

Thanks CoNtAcT, nice bench test results you have there.

Thanks Mad Man, you suppose I’ll get an over clocking ticket?

[theoldtimer]

I flashed the 905 bios today and tested the HTT clocks compared to the 801 bios. With the 801 bios when testing the 1055T it would boot @ 373HTT and would run wPrime-32 @ 10x407 in windows but the best I could get out of the 905 bios was boot @373HTT then run wprime-32 @10x405HTT in Windows. @406HTT the system would crash at the desktop or while loading any program or bench. There may be a setting in which bios 905 and 801 are equal for HTT over clocking but I didn’t find it during my limited testing, although your results may vary.

The 905 bios may be better than the 801 in many ways but for me testing HTT clocks the 801 seems a little better. In all likelihood I’ll flash back to 801 before my dice runs.

SS of wPrime-32 @405HTT on the 905 bios



I did test two other sets of ram to see if the set I have been using is helping me over clock the HTT or if any of my sets would do. I don’t claim to be any kind of an expert with ram or much of anything else really but I did spend about an hour with each set trying different settings (timings). Some of the members here may have the skills to get my other two sets of memory to work when over clocking the HTT but I didn’t have much luck with my other two sets. For me the Corsair GT 2000 CL8 set gets it done they worked well on my CH3 also.

In the SS below the set on the upper left is the Corsair i7 1600 CL9 3x2GB set (max boot was 260HTT failed 270HTT boot. The set on the upper right is Gskill i7 1600 CL6-7-6 3x2GB max boot was 320HTT failed 330HTT boot. The bottom set is the set I have been using for most of my testing on AMD systems Corsair GT 2000 CL8 2x2GB max boot 373HTT failed 375 boot.


Corsair i7 1600 CL9 3x2GB set (max boot was 260HTT failed 270HTT boot.

Corsair GT 2000 CL8 2x2GB max boot 373HTT failed 375 boot.

Hmmm..... Very Interesting....

Just out of curiosity OT, how well does that G.Skill clock with multi's (not high HTref)?

As unlikely as it seems (in my mind anyway ) maybe it is my memory thats keeping me below 300 HT.
Whats wierd to me is the fact that it actually clocks pretty well as long as I keep the Ht down (~1900 8-9-8).

I get off work in a couple hours, you've given me some good ideas!

L8r.... Dave

I really haven't tried clocking the Gskills in the CH4F when using mostly the multi. They worked ok in the CHIII earlier though but nothing like the Corsair GTs.

I pulled the chiller off the 1055T this afternoon and installed air cooling on the processor. The chiller was helping the chip with the HTT some as 390 is about the best HTT @ the x10 multi I could get it ti complete wPrime-32. I tried 396 and 395 a couple of times but the system locked about a third of the way through the run.

[MagicSpEctRe]

oh man, that's so wild,amazing clock u got there

[CoNtAcT]

what is the VCore from the board NB @400+ htt?

[theoldtimer]

Thanks, the 1055T is a nice chip.

what is the VCore from the board NB @400+ htt?

The vcore needed varies by the chip (I've tested three, two 1090T's and one 1055T). One 1090 did it on default vcore LLC enabled, one needed 1.4V+ and this 1055 needed 1.45-1.47v to do 400. It may do400 on less vcore if I back some of the setting down a bit (mem, NB)? That was in chilled water. It needed more vcore @407HTT.

[FlanK3r]

crazy HT link, test please Winrar bench with so high HT link, curious, if will the best combination (high HT and NB for RAR performance) .

[CoNtAcT]

at morning i test my htt from Gigabyte 790FXTA UD5, wiht 1,3V NB i can start @353 MHZ. I no longer wanted to give the NB vcore, because they are already at 59 degrees Celsius

Starting @353 is good

crazy HT link, test please Winrar bench with so high HT link, curious, if will the best combination (high HT and NB for RAR performance) .

I still have the system under air cooling so the HTT max is 396 and more voltage above 1.47v doesn’t help with getting a higher HTT. I ran the Winrar bench test with the 1055T @ the above HTT and then tried other setting using a higher multi with lower HTT for comparison. The problem with that being that the processor plus NB multis on the 1055T are both very limited so trying to find a combination where the CPU, memory, NB and link speeds are similar to the 396HTT test is difficult at best.

I finally just pulled the 1055 then installed the 1090T which makes it easier to come up with a settings combination for a comparison (high HTT low multi to high multi low HTT).

1055t @10x396=3960MHz


1055t@13x305=3965MHz


1090t @10x396=3960MHz



1090t@16.5x240=3973MHz

[FlanK3r]

Oldtimer, thank very much!

[theoldtimer]

Tested some of the limits of both the 1055 and 1090 today. Still on air cooling.

1055T 4x100=401MHz x4-multi and 100HTT is as low as I could go in the bios (Ram, NB, HT-link @auto)



1090T 4x100=401MHz same minimum as the 1055 (Ram, NB, HT-link @auto)


1090T 31.5x100=3160MHz 31.5 was the max multi that would boot the NB, HT-link was set to the max multis also I think the ram was @ auto

[FlanK3r]

nice and very interesting...seems low busspeed make degradation performance (or RAM???is only 800 MHz). And nice low clocked Thuban :-)

[Daveburt714]

Hi oldtimer, is this the GT kit your using?

http://www.microcenter.com/single_pr...uct_id=0318705

I know there are two similar kits, if these are the hypers it seems like a decent deal....

Those are the ones Dave I use them in every benching rig that only needs dual channel. I'm thinking about picking up another set for the gaming rig I'm building around the 1055T? There may be another brand that is as good in the AMD stuff as these GTs? Maybe at this price or even at a better price I don't really know? What I do know is these GT's work well in the AMD systems I have. I'm not as good as some of the people here when it comes to ram clocking so the GT's help a bunch. You already have some very good hardware and if you can swing it, the GT's should help with the 1055T.

[Daveburt714]

Hey OT,

I went and bought that kit today...
The only thing I noticed thats different is your kit has the code "GX3M2A" mine is "GX3M3A". Their both revision 2.1 so I'm assuming these are Hypers too...

I've been looking at some of your results to get me in the ballpark, but I noticed you don't show RAM voltage in any of your SS's...

What Ram voltages were you running? Any clue whats safe and stays within warranty?

Thanks.... Dave

When I get my other set I should be able to tell after a few tests if they are Hypers.

Sorry Dave I didn't check what the Corsair warranty states for max voltage.

I don't push as much juice through them as some here do but I run at least 1.65v most of the time. The most voltage that I have used is some where around 1.72v +/- but for most of the tests I set them 1.67-1.70v. If I plan to run a bunch of different tests one after the other using somewhat tight timings I set them @1.70v and forget about it. I don't know how well they would handle that voltage 24/7 as I don't run anything 24/7 overclocked/overvolted.

I'm looking forward to see your tet results Dave.

[Daveburt714]

Did some rough testing last night.
I think its safe to say they're still Hypers...

Thanks for the voltage tips!
I pushed it a little (~1.7v) but it didn't seem to offer much, of course this bios overvolts memory a little too.

[theoldtimer]

I finally got the gaming rig together for testing but I figure I have a long way to go before I find the final setup. As you’ll notice right away I’m a little more into fuction than fashion.

The Case is a Cooler Master 932 HAF.

The water cooling system consists of one swiftech pump and a Chevy van heater core for the radiator using the existing cooler master top fan with two 120MM pusher fans mounted to the bottom of the radiator. I mounted an AMD CPU heat sink fan over the NB heat sink to improve it’s cooling.








First few tests not really sure if it has much more in it using ambient water cooling.
