GSkill F1-4400DSU2-1GBFC & Asus A8R32-MVP problem

[MAXLD]

Hi, first of all, my configuration:
AMD A64 3000+
Asus A8R32-MVP Deluxe (latest bios, 0602)
Enermax Liberty 500W

I have GSkill F1-4400DSU2-1GBFC (DDR550) memory modules but I can't put them working at 275Mhz, with my current motherboard. They supose to work properly at that speed...
In my old one (Asus A8N-SLi Premium) I was using them at 285MHz 1:1 (2.5-4-4-8, not sure about the exact values) @ 2.85V with no problem at all.

But with my current one (Asus A8R32-MVP Deluxe) I have SuperPi (2MB) errors with all the timing configurations I try.
The last ones I tried (3-6-6-11, indicated by SPD):

With those settings I get 1 error after starting SuperPI 2MB... :(
I've tried 2T (CMD-ADDR Timing) also.... no improvements.
I've updated my mboard bios but no improvements also.

Could someone help me and tell me what could be the problem? :)

Thank you. :)


PS: I've tried to contact the european Gskill support (eurotech@gskill.com), asking if they could tell me the most reliable timing settings, but I have no reply yet...

so not user friendly hahahaaa

well i get to say we don't have this motherboard and it is hard to give advice

___CAS (CL)_____________________2.5
___TRAS________________________8
___TRP_________________________4
___TRCD________________________4
___TRRD________________________2
___TRC_________________________11
___TRFC________________________19
___TRWT________________________3

Hi, thank you. :) I'm not sure, but I think I've already tried those timings...:)
I've received an answer from eurotech@gskill.com a few hours ago:


It is important to run your memory at 2.5-4-4-8 @275MHz
- CAS Latency (CL) 2.5
- TRAS 8
- TRP 4
- TRCD 4
- TRRD 2
- TRC 7
- TRFC 14
- TRWT 3

- TREF (You can leave AUTO)
- DDR Input Stroke Skew (You can leave AUTO)
- DDR Data Sriving Strenght (You can leave AUTO)
- Burst20pt

- Read Preamble (You can leave AUTO)
- Asyc Latency (You can leave AUTO)
- CMD-ADDR (You can leave AUTO)
- Burst Length (You can leave AUTO)
- Hardware Memory Hole (You can leave AUTO)

Well, I've tried those settings and some variantions but: no improvements. :(
I think I'll send them back to the store and then to RMA... :(
