Need Memory Pros to solve my problem with DDR3 memory on GIGABYTE MA770T-UD3P

[St Devious]

Hello to all the people here on XS.

I'll try to describe the problem best I can. You can ask me any questions if you have any doubt.

So I'm overclocking the Athlon II X2 250 on GIGABYTE MA770T-UD3P.

The settings that are confirmed to work which have been tested with Crucial DDR3 4GB (2x2GB) rated to run at 1333 MHz kit http://www.newegg.com/Product/Product.aspx?Item=N82E16820148262 is

CPU Clock - 3855 MHz
CPU Northbridge Freq. - 2570 MHz
Bus Clock - 257 MHz
HT Link - 2570 MHz
Memory Clock Multiplier - x6.66
Memory Speed - 1712 MHz
CPU NB VID - +0.100V
CPU Voltage - +0.125V
DRAM Voltage - 1.800V
DDR Voltage Control - Normal (0.9V)
All other voltages are at Normal

Now I try to run Kingston RAM (http://www.newegg.com/Product/Product.aspx?Item=N82E16820104107) at the exact same settings and the board doesn't boot. I tried to lower the Bus Speed to lower the speed on the memory and the Max speed I can run this Kit on is 1579 MHz with the x6.66 Multiplier and Bus Speed 237 MHz.

If I set the multiplier to x8.00 and adjust the Bus Speed to 225 to have the RAM run at 1800 MHz, the board boots fine. Infact the board boots fine even at 235 MHz Bus Speed so that the memory speed is 1880 MHz. So there doesn't seem to be anything wrong with RAM, but I'm surprised that it runs at quite a lower speed than the 1333 MHz rated kit with a x6.66 Multiplier.

Furthermore, my max OC on this board is using the Crucial Memory. The settings are as follows

CPU Multiplier - 13.5 Speed - 3955MHz
CPU Northbridge Multiplier - 10 Speed - 2930 MHz
Bus Speed - 293 MHz
HTLink Speed - 2930 MHz
Memory Multiplier - x5.33 Speed - 1561 MHz Timings - 7-6-6-15 1T

CPU VCore +0.125V
CPU NB Voltage +0.75V
Memory Voltage 1.8V
All other voltages normal


I tried to run the HyperX RAM at the same timings and speed, and the board wouldn't boot. To boot I have had to lower the Bus Speed to 290 MHz and loosen the timings to 9-9-9-24 2T (Still testing on the timings). I'm still puzzled that why HyperX is not running better than the other RAM at lower multipliers since it is rated for higher speed. I would like to tell you that the Crucial kit uses D9JNM chips on it. I don't know what HyperX uses, but could that be the deciding factor ?

i have the same board and have problem running lower then cl8.

[richierich]

i thought the Regor chips only had a max of ddr3 1333 controller?

[soundood]

PM chew*, hes our local memory expert.

[Maregg]

Pfff, I have the same board and I had problem running my memory modules at their rated specs !!! Memory is G.skill ddr3-1600 CL8.

Took me forever to find that the board defaulted to 1.6v while the memory demanded 1.65. However, even at 1.65v (effectively 1.645v), the board will sometimes lock at the memory boot test. Before adjusting the voltage, it would crash on memtest, prime blend and in friggin IE.

Good luck, this board seems fragile with regards to memory. I'm waiting patiently for a more robust bios firmware.

This is true. I doubt you will be able to do 1600mhz+. Try 1333 with tighter timings and high NB frequency, you'll like it better anyway :up:

[Smartidiot89]

This is true. I doubt you will be able to do 1600mhz+. Try 1333 with tighter timings and high NB frequency, you'll like it better anyway :up:
Also doubt it will be able to pull of 1600mhz, Phenom II gains more from a lower freq/tight timings clock anyways:up:

Memory looks like D9KPT.

Knowing what ic's you are using and what particular IC's like is half the battle.......After you tune so many diff IC's you tend to have a ballpark of where to start.

Lose the HT link speed.....it will gain you nothing.

Best if run between 2000-2250......

D9KPT likes 1.7v 6-6-6-24-28 1T 1333 + if you can I reccomend running 90NS... subtimings are going to be sticks and cpu dependant.

Alternative is 1.7v 7-7-7-24-28 or 30 1T 1600+ 90Ns if possible, and once again subtimings are ram/cpu dependant.

Play with drive strengths if available......

Asus tends to clock 2x2 gig better......loves elpida and d9 KPT not partial to d9 gts/gtr board overvolts vdimm.

Giga tends to clock 2x1 gig better......loves d9gts/gtr not to partial to KPT board undervolts vdimm.

MSI I haven't really played with to much.

D9 KPT likes a medium drive.

FYI for others reading.

d9gts likes a strong drive. 1.9- 2.2V range 6-6-5-15-11 1T 90 ns 1600/ 7-6-5 or 6 15-11 for 1700+

Elpida likes a weak drive. 1.6-1.7v range 6-6-5 OR 6 18-24 1t 90 NS 1600-1800 RANGE......CPU MUST BE COLD FOR HIGH RANGE ( phase change ), ln2 + High NB will stress them and they will need to be backed off.

Power chips like a medium drive. 1.55-1.7 v range 6-6-6-24-28 1T 110ns 1333+ ( these do better low and tight versus 7-7-7 1600+ )

D9 KPT 1.65- 1.8v range

For high end volt range active cooling is a must.......

Guys :)

This is my setting for daily used ....

Its so hard to get NB 2700+

Memmory : OCZ Reaper 1333 CL 6 ( D9JNL ) :up:

IBT stresses core only fyi

Try prime blend for 3 hours ;)

@chew* ... Ok I will Update soon brother :)

Sorry I'm still very new with the AMD brand.

I had a very hard time pairing X2-550, MA-GA770T-UD3P and 2 stick of G.SKILL F3-12800CL8D wich is rated at CL8-8-8-21 1.65v.
Bios automatic defaulted the ram at CL9 ddr-1333 1.6v and my system was rock solid at those specs.
When I try to run the sticks at their rated spec, the system becomes very unstable. Forcing the voltage to 1.65 seems to make it more stable but still have issues.
I almost RMA'ed the ram thinking it was unable to deliver on said specs.

Now, reading from this thread, you guys seem to say that the limitation is actually comming from the X2-550 «weak» IMC ? Even more disturbing, that the Phenom II is taking more advantage from low speed, tight timings ? So trying to reach the ram spec would be crippling my system ?

I'll definitly try to run the ram at DDR3-1333 CL7 and see if they are stable at that speed.

[Kazzamm]

Not that I understand 90% of what I am reading but the OP has a Athlon 2-250. Not a Phenom 2-550. Just my 2c.

Yeah, with AMD, people are not used to how to tune the ram. Don't RMA just yet.

In order to get that ram to run at spec, you will likely have to give a bump in the CPU/NB voltage and NB frequency....as well as increasing NB Voltage.

Phenom II likes tight timings and 1600MHz and below. However, if you tune sub timings, and drive strengths etc etc then you can run higher speeds.

Trying to reach your spec will not cripple your system, its just easier on the IMC to go with lower speeds and tighter timings. However if you follow what I said above you will most likely be able to get them to run at stock specs.

Yes but they are the same architecture with cache cut out. Similar ram clocking/IMC.

[chew*]

Fwiw Not all my amd's are PH II. some are sempron and some are older 939's.....the same methodology applies.

[mav2000]

I am not able to run stock speed with the OCZ 1600 AMD kit platinum edition. I can run 1333 6-6-5-18, but thats the best I can get out of them. Tried 1.71V 7-7-7-24, but it says that my windows installation is corrupted due to some hardware changes, and when I put in the vista CD it starts with loading the files and then gives the same message...something called winlogon is i am right..so am stuck right now. Am on an unlocked 720 be and an msi gd70 with the 1.5b4 bios....Chew please help.

[chew*]

beleive i needed 1.69v on the MSI for 7-7-7-24-28 on 13B6.

The 720 BE IMC isn't all that great......that might cause you issues.

[mav2000]

Looks like thats what it is then...thanks for the reply...will hold onto these till I can get my grubby hands on a 955 or 965...anyone selling a 955 cheap????

I get the same kind of error when the memory is OCed too much and not stable. Win doesn't start and says that ntoskrnl.exe or winload.exe file maybe corrupt and asks me to insert OS DVD to repair. I did a repair but it found nothing.

Additionally I found that on returning to stock settings or lowering the memory OC, the Win would start normally.

it's best to check the ram with memtest86 before starting windows, at least for a couple of minutes

[St Devious]

How is OCCT Large Transfer set + Orthos Blend running in Windows for testing RAM ?

[Zeus]

What beta means is that running memtest 86 for stabilty check helps you prevent corrupting windows.

Trying to boot straight into windows with unstable ram can easily fubar your os.

[beta]

yes I meant exactly that, thanks Zeus.

also you can start memtest86 from any bootable linux livecd.
