Hi everybody!
I have buy yesterday new custom DAW!
Everything was great untill i have realize that i have problem with the RAM memory.
Default settings for this Kingston HyperX RAM(800 MHz-6400) is 667 Mhz by 5-5-5-15.
DESCRIPTION OF RAM MEMORY:
Kingston's KHX6400D2LLK2/2G is a kit of two low-latency 128M x 64-bit 1GB (1024MB) DDR2-
800 CL4 SDRAM (Synchronous DRAM) memory modules, based on sixteen 64M x 8-bit DDR2
FBGA components per module. Total kit capacity is 2GB (2048MB). Each module pair has been
tested to run at DDR2 800MHz at low latency timing of 4-4-4-12 at 2.0V. The SPD is programmed
to JEDEC standard latency 667Mhz timing of 5-5-5-15 at 1.8V. Each 240-pin DIMM uses gold
contact fingers and requires +1.8V. The electrical and mechanical specifications are as follows:
FEATURES:
Power supply : Vdd: 1.8V ± 0.1V, Vddq: 1.8V ± 0.1V
Double-data-rate architecture; two data transfers per clock cycle
Bidirectional data strobe(DQS)
Differential clock inputs (CK and CK)
DLL aligns DQ and DQS transition with CK transition
Programmable Read latency 3, 4, 5 (clock)
Burst Length: 4, 8 (Interleave/nibble sequential)
Programmable Burst type (sequential & interleave)
Timing Reference: 667MHz 5-5-5-15 at +1.8V / 800MHz 4-4-4-12 at +2.0V
Edge aligned data output, center aligned data input
First of all,i was update BIOS to a last revision and then change the frequency from 667 to a 800 MHz,and then timing settings.
After that i have restart comp and i heard 3 bipp!
I have cheked my motherboard specification and there was :
System Memory Features
The board has four DIMM sockets and supports the following memory features:
1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.
8 GB maximum total system memory using DDR2 667 or DDR2 800 DIMMs
Minimum total system memory: 512 MB
Non-ECC DIMMs
Serial Presence Detect
DDR2 800 or DDR2 667 MHz SDRAM DIMMs
DDR2 667 SIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP)
DDR2 800 SIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP)
At the end,can i make that my HyperX memory work with those settings 4-4-4-12 at 800 MHz???
Thanks
