Biostar Tpower X58 pushed i7 920 to 4515mhz

[Pt1t]

my chip didnt have issues benching all benchmarks at 221*21 on UD5 on SS with -45C to -50C

i guess it's probably a cold bug somewhere lower as your cascade would do what... -100C or so right



shame we cant run higher BCLK
i'd love to give all those 965 boys a hard time with a 920 chip

i can bench all arround 4.6Ghz , but with LN2 @ 40 - 45° under that i cant boot with high Bclk. Under cascade i can boot with 133mhz Blck but no more.

AMD cold bug used to be manifested with high HTT

Little improvement with new bios and CPU cooled by -20° ln2

CPU : Core i7 920
Mobo : Biostar Tpower X58 ES
RAM : 3 X 1go A-DATA 1600x
VGA : Gigabyte 9800GT
PSU : Gigabyte Odin 1200w
Cooling CPU : Dragon Evo @ -20°

I feel good seeing you putting that EVO to good use

[Cold Fussion]

Any word on Australian availability?

[Pt1t]

Some efficienty test with last bios in date :

965xe under Noctua 1.55v
3*1go A-Data 1600X 1.9v
VTT 1.5v
Memory Timing 7-6-5-15 in bios , other timing in auto.

@Pt1t,

May I know how to set the memory divider uisng 2:10. Coz I have this mobo but my mobo only allwo me to set 2:6 and 2:8 divider only. Using the latest bios from official webby but still limited to 2 memory divider only=(

that is not board, that CPU's , some got more memory divider unlocked, some not

[memory]

Thks for the prompt reply...

But my i7 920 on Asus P6T Dlx and Gigabyte X58 UD5 allow me to select the memory divider for 2:10, 2:12 and so on. I am so dissapointed that the same pair of my memory that can go more than 1600mhz on other mobos cannot go more than 1600mhz on this Biostar due to the memory divider=(

I will ask why to biostar monday

Really appreciate yr help.

Hope Biostar will release newer bios to solve the memory divider locking issues.

Anyway just to feedback that this mobo is more stable than my Asus P6T Dlx and giga X58 UD5 in terms of cpu clock speed

I wonder what the temp is with that corei7 at 4.3ghz ! Is it below 60 oC!

[Pt1t]

Surprise !!!

This BIOS can for support uncore to 4266MHz
and DRAM to 2133MHz for ''ALL 920/940 CPUs ''
1. uncore Freq must always > = 2 X DRAM Freq ( * BIOS will check your setting is >= 2X DARM Freq, otherwise need forced to 1066)
2. You need to set '' uncore Freq '' first then go for '' DRAM ratio''. (Higher DRAM Freq means higher uncore Freq)
3. For Core i7 965XE , the uncore ratio is adjustable without any problem. This BIOS will access for some '' unlock''
920/940 CPUs. But if the CPU was locked , it won't work.

nice Thomas
i got it today and i will test soon and i hope with that no one will be disappointed

Its funny, I got a cold boot bug at -40c~ with my i920/P6T DLX.
After you boot, there is no problem to work/bench at -60c or so.
I discovered it with my Dry Ice run about two weeks ago.
Do you guys think its a Mobo or CPU issue ?

i have acess for all dividers and uncore frequency but my cpu is locked and i can only use RAM at 800MHz or 1066Mhz any other setting will not work and i found issue I can not OC after setting even AUTO.
Already fix in the new bios.

and bad news for you ! your 940B0 ColdBoot @ -25°

bad news ....

[eva2000]

time to stick with retail cpus hehe

[Pt1t]

time to stick with retail cpus hehe

yes , i have 965xe retail but not so good ... i ordered other one same FPO than andre and i m looking for 920 like yours

The 965xe does 3dmark 2005 to 4.5Ghz aircooled (~5°) but only 4.9Ghz under -100°

[SirKronan]

Would this be a better bet than the EVGA X58 board? I'm on the hunt now ... looking to upgrade soon.

Keep in mind if you don't mind 2 yr. instead of lifetime, you can get the EVGA for $250 AR now.

[Elloquin]

T-Power X58 on H20



Oh and max BCLK 222 Copper True



was a while ago had some bios settings incorrectly set :P

[SirKronan]

Link to someone else's BIOS screens. Hope it's helpful ...

Also, if anyone has any input regarding my inquiry above, I greatly would appreciate it!

[Pt1t]

Today i pushed BLCK a little higher than 222Mhz ....

CPU @ -20° under dryce ^^

voltage used :


* CPU Vcore : +0.020V
* CPU VTT : 1.40V
* CPU PLL : 1.80V
* SB VCC : Auto
* DRAM Voltage : 1.65V

2 bad videos of me playing the 920 on the tpower X58 and Dryice

Maxscreen on tpower X58 with 1,4V vcore and 1,45V VTT :o



And a wprime 32M @ 4500Mhz with very low vcore for -20° ... Dryice without acetone.



I will test this cpu later under my cascade ... If it likes cold ..and also on different motherboard.
