Re: Overclocking a E5300 and EP43-DS3 ? basic help needed
I will put a answer to your questions by some of your ??'s so you know what they are.
I would advise you read this guide as it will explain alot of that to you. It was written for P45 though, but some of the general terms are the same and it will help you a lot I think.
As for 1:1, that is up to you if you want to use it. It is not as good as one may think and was really only important/better in the past on older boards. This is not so much the truth anymore at all so you do not have to run 1:1
BIOS Memory Multiplier option of 2.00 is 1:1 with the FSB, so you would need to adjust your FSB to 533 to use 1:1 and that may not be possible with your CPU.
Here is what I would advise you try for 3.3Ghz and your hardware, this is NOT 1:1
MB Intelligent Tweaker(M.I.T.)
Robust Graphics Booster ...............: Auto or Fast
CPU Clock Ratio ..........................: 13X << Set to x10
Fine CPU Clock Ratio.....................: ?? << this if for some .5 CPU multi's on certain 45nm CPU's
CPU Frequency ...........................: 3.33 Ghz
Clock Chip Control
Standard Clock Control
CPU Host Clock Control..................: [Enabled]
CPU Host Frequency (Mhz) ............: ????? << FSB, set to 333
PCI Express Frequency (Mhz) .........: ????? << Set to 100
Advanced Clock Control [Press Enter]
CPU Clock Drive...........................: 800mV
PCI Express Clock Drive.................: 900mV
CPU Clock Skew (ps)....................: 0ps
MCH Clock Skew (ps)...................: 0ps
DRAM Performance Control
Performance Enhance...................: [STANDARD]
Extreme Memory Profile (X.M.P.).....: Dont have this option << this is memory specific, if your ram is not XMP or EPP Programmed you will not see this. Disabled anyway
(G)MCH Frequency Latch...............: ?????????? << Set to Auto
System Memory Multiplier ..............: ??????????? <<< Set to 3.20B (FSB x this = Ram speed)
Memory Frequency (Mhz) ..............: 1066 per above (333 FSB X 3.20B = 1066Mhz)
DRAM Timing Selectable ................: [Manual]
Standard Timing Control
CAS Latency Time........................ 5 (??? should this match my memory timings as per the box?) << Yes, set to ram spec amount
tRCD ......................................... 5
tRP'........................................... 5
tRAS.......................................... 18
Advanced Timing Control
tRRD........................................... 3 - Auto 3-4
tWTR.......................................... 3 - Auto 3-6
tWR............................................ 6 - Auto 4-6
tRFC........................................... 46 - Auto 52-62 (Set 52 or more for now)
tRTP........................................... 3 - Auto 3-5
Command Rate (CMD) ....................:0 - Auto 1-2 (Set 2 for now)
Channel A
Static tRead Value.........................:3 - Auto 5-8 (Set 6-7 for now)
tRD Phase0 Adjustment...................:0 - Auto
tRD Phase1 Adjustment...................:0 - Auto
tRD Phase2 Adjustment .................:0 - Auto
tRD Phase3 Adjustment..................:0 - Auto
Trd2rd(Different Rank)....................:6 - Auto
Twr2wr(Different Rank)...................:6 - Auto
Twr2rd(Different Rank)...................:5 - Auto
Trd2wr(Same/Diff Rank)..................:8 - Auto
Dimm1 Clock Skew Control...............: Auto
Dimm2 Clock Skew Control...............: Auto
DDR Write Training.........................: Auto
Channel B
Same as Channel A
CPU
CPU Vcore….……….........................: 1.25000V << More, all up to your CPU of course, maybe 1.28-1.38 or so for 3.3Ghz
CPU Termination…..... 1.200V*.......: Auto << Set 1.225-1.3 for 3.3Ghz. This is Vtt I believe in DFI BIOS
CPU PLL…………………....1.500V*.......: Auto Set 1.5, you may need a bit more at 333 FSB or above though.
CPU Referen.…………....0.760V*.......: Auto
MCH/ICH
MCH Core…………….....1.100V...........: 1.200V Often for 4GB you need 1.20-1.24, looks like you know what you are doing here
MCH Reference….…….0.760V...........; Auto
MCH/DRAM Ref.…......0.900V...........: Auto
ICH I/O……………….....1.500V............: Auto
DRAM
DRAM Voltage ……....1.800V............: 1.900V << Set to your ram spec, normally 1.9-2.1V
DRAM Termination .…0.900V............: Auto
Channel A Reference 0.900V............: Auto
Channel B Reference 0.900V............: Auto
Advanced Settings
Limit CPUID Max. to 3.....................: [Disabled]
No-Execute Memory Protect............: [Enabled]
CPU Enhanced Halt (C1E)................: [Enabled] << Disable for overclocking
CPU Thermal Monitor 2(TM2) ...........: [Enabled]
CPU EIST Function.........................: [Enabled] << Disable for overclocking
