AMD Phenom II X6 1055T can run G.Skill DDR3-2000 CL7-9-7 @ ASUS CROSSHAIR IV FORMULA

[OCman XPC]

how about phenom II x6 with 790FX chipset??? would it be able to run DDR2000 ?

I will try Phenom II X6 with 790FX chipset .

Currently , I just make sure Phenom II X6 with only ASUS 890FX Motherboard can run DDR3-2000 , and more DDR3-2060 passed .

To testing DDR3-2060 CL7 @ dual channel 4x2GB
Hyper PI setting caculation 32M , running 12 Cores .

LOOP 9


LOOP 23


2 Cores finished


Finally , 12 Cores finished

[OCman XPC]

Yep.

I'm RMA'ing my Gigabyte board due to some problems I'm having.

This bouad has a 940 Mhz wall, however it's a Revision 1.0 board. Rev 2 is already out. If I get a Rev. 2 board back I'll be sure to test ram clocks.

Because I tried to using Phenom II X4 run peak DDR3-1900MHz @ ASUS CH4F , AMD improve the IMC of Phenom II X6 CPU
Recommand using AMD Phenom II X6 CPU to runnig over DDR3-2000MHz .

Interesting OCman..... thanks for sharing.

[Andi64]

Can you run DDR3-2000 at 1T command rate?

[map01ch]

How is it with corsair Dominator 8GB?

How is it with corsair Dominator 8GB?

Because I have no corsair Dominator memory , I checked CROSSHAIR IV FORMULA memory support QVL list from ASUS web . Currently , I did not found it .

All this is great but how's prime 95 blend.

Seems to me all that memory speed gets wasted on an IMC that still has a limitation in prime 95

I tried my AMD Phenom II x6 1055T with ASUS M4A79T- Deluxe , my best runnig DDR3-1800 CL8 1T ,

It seems that running DDR3-2000 @ AMD BEST Match are Phenom II x6 with 800 series chipset .

[Zeus]

That's pretty but trcd is waaay too loose. Can you give some more volts and lock timings down?

It is seem that running DDR3-2000 @ AMD BEST Match are Phenom II x6 with AMD 800 series chipset .

You should fix that to it seems that benching @ 2000 is best on 800 chipset.

Unless of course you can run say prime 95 blend at 2000 ram at normal average user clock speeds.

[sandlewood]

thanks for sharring
can test on AMD 785 chipset?

[Barr3l Rid3r]

and they say it' special for AMD? I can see no difference to my old ripjaws.

[luf1c3r]

Could you give us information about operation of the ram with just two sticks instead of four? A comparative power to see that you can take with other clubs such as the one just put up our friend here.

AMD Phneom II X6 with M4A79T Deluxe , do my best to improve tRCD timing DDR3-1800 7-8-7-24 ,


Pass Hyper PI 32M


Pass MemTest 700%

[OCman XPC]

Nice frequency, but NB @ 2000 =

OC 4GHz , 250MHz x16
CPU/NB (Uncore) Freq.=2500MHz
DDR3-2000 CL7-9-7-28
Burning 2Hr30min, Memtest 250% stable
Task Manager , CPU Usage 100% , Physical Memory usage 7.6GB


Test Hyper PI 32M/ 12Cores using CPU/NB Freq.=2500 MHz , spend 25 min.28sec. , using CPU/NB Freq.=2000 MHz , spend 31min.57sec. ,
Inrease Uncore Frequency is helpful .

my x4 955 had problems running anything above 1500 in the first two memory slots, I guess the x6's can handle it better with the improved IMC? (also yay firstpost).

[BeepBeep2]

Yup. But always use the back slots...they are better.

[Shadowized]

yeah I've been using the two farthest slots for a while, it just makes no sense that every guide I've read suggests the two closest to the CPU are the best

may have to pickup a kit of this memory when my x6 1055 gets here and see if I can get 1700 6-6-6-16-1t or something out of it on the m4a79t

[BeepBeep2]

That won't happen without Hyper chips.

Look up the ram in my sig and buy some. (In the US it's ~$200...) Guaranteed 1750 6-6-6-18. Hyper is EOL so buy fast.

[OCman XPC]

All this is great but how's prime 95 blend.

Seems to me all that memory speed gets wasted on an IMC that still has a limitation in prime 95

OC 4GHz , 250MHzx16 ,
CPU/NB Frequency =2500MHz , DDR3-2000 CL7-9-7 1T
Prime 95 blend

[chew*]

OC 4GHz , 250MHzx16 ,
CPU/NB Frequency =2500MHz , DDR3-2000 CL7-9-7 1T
Prime 95 blend

I appreciate the effort but how about say 1 hour min on that IMC.

1 hour is not so fad considering the 30 min 32m tests that i know must have been boring to watch.

Hello, it's not the subject of this topic but what do you do to have multiplier 16X on the 1055T, I can not have more than 14 on my 1055T?

Hello, it's not the subject of this topic but what do you do to have multiplier 16X on the 1055T, I can not have more than 14 on my 1055T?

ASUS Crosshair IV Formula allows to lock turbo multipliers on all cores so you can choose up to 16

[DR G frag]

I have a Crosshair IV formula too (with bios 801) and I can't arrive to have multiplier 15 or 16 (in the bios I can choose it but on cpu-Z (windows7-64bits) I only see multiplier 14.
What is the procedure to have multiplier 15 or 16 with the 1055T? it's in the bios? in TurboV evo? with other application?
To don't disturb the aim of this tread you can answer me in Private message.
Thanks

[BeepBeep2]

I honestly do not know...I do not own this board.
