NVidia Control Panel (NCPL) carries additional settings in memory tab besides the standard 5-5-5-18-24 values. I will list them here. These are the settings for my system, followed by max value in that range.


tRRD = 3 , max 5
tFAW = 13 , max 20
tWRRD = 1 , max 4
tWTR = 3 , max 3
tRDRD = 2 , max 5
tWRWR = 1 , max 3


When overclocking the mainboard, should these settings be relaxed as well?

The reason I ask is because I'm into 2nd wave of OC trials. I can set HT in BIOS to 260, boot into Windows 7, and go into Nvidia control panel to set CPU multiplier to x15. All is well. I can run Windows performance test and it passes fine. Now up to 7.5 btw for the CPU and RAM.

Problem is, when I attempt to load a profile with these settings, the system blows up. I'm starting to think that one of the settings being loaded by NCPL is causing the instability and that's not seen if I just bring up NCPL and only set the CPU multiplier. I can't think of any other reason why it's okay to set the clock manually this way and not through a profile load.

Has anyone else observed this situation and have a solution or recommendation?

Thanks and Cheers,

You might want to try some other software for overclocking that gives you the option to increase the voltages of your NB - CPU voltage.

You can try to use K10Stat to do this. I'm not sure if there is any software utilities that will allow you to adjust the CPU to NB multi for the IMC though. :/ Extreme Systems forum talks about it a bit too. This should help stablize your NB Frequencies and you can also use K10stat to underclock your cpu depending on the way you set up the program.


Oh yeah another app is phenommsrtweaker

I have not used either of these app's but I know some peeps that have and they seemed to like it for adjusting the CPU-NB voltage.

ok so now that the core clock is set to 3,2ghz.
CPUZ is showing me that the Bus speed is 214,3mhz and something called HT Link is also 214,3mhz ( HT would be Hyper Transport ) but i've seen screens from other peoples cpuz and the value for HT link was like 2000 and something.
Maybe its the Motherboard fault?? i dont know. Anyone can tell me is it alright ??

ok ... Ntune solved this problem also. But did anyone had a HT transport value above 1000 mhz ?? the multilier is x5 to HT ?? DSid anyone tried higher ??

These boards are HT 1.0, so 1000mhz(5 x 200 ref clock) is default but will rise when you increase the ref clock.
As will the NB freq and ram freq.

As for running HT higher than 1000mhz,there is no real gain from running it higher.
General rule is to keep it close to 1000mhz.

Good luck

It's probably best to only use the tools for changing the cpu multi and ref clock,all other changes should be done in the bios.

As for the timings you listed,none off those should/need to be changed.
The only ones you need to worry about is 5-5-5-18-24.

Yes, Gyro, that's all I was using NCPL for, other than to also commit the changes to a profile.

It appears I have some other voltages I need to tend to...

Thanks,

@GR8SHO, i have to agree, worry about the main timing for your ram. if you start adjusting the wrong settings you could seriously hurt you ram. i adjust everything in bios except for my ram. the only thing i do to my ram is set basic timing and voltage and the normal 5-5-5-12-18-2T, if i set my ram for 1066mhz i have to add an extra .05volt, and set timing to 5-7-7-16-28-2T


@SLAWKO
my ht link is at 1004, but my nb frequency is at 1607.4 .. the reason my nb is higher is because i have my ram set to 1066 mode in bios. to drop that to 1k i would have to lower my ram divider to 800mhz. if you overclocking using your bus it will go above 1k unless you drop the ram speed, and your ht link will go over 1k unless you drop the divider down a bit. as GYRO said, there is no gain in the ht being over 1k, but it can limit your oc if it is, and can make it unstable.

I have not used either of these app's but I know some peeps that have and they seemed to like it for adjusting the CPU-NB voltage.


Okay, maybe this is the missing ingredient. Perhaps it is assumed that if someone is going to OC the mainboard, that they're familiar with all the knobs, but not the case here.

I'm going to look into the first tool first. Before I start, I have a few simple questions.
  1. Is there a rule of thumb that should be followed when raising the CPU-NB voltage?
  2. The BIOS also has a 200mv Offset under an Advanced Setting. Will this accomplish in some basic way what we're trying to do here for pushing the mainboard speed?

Thanks!

be easy with NB voltage. i wouldn't recommend going over 1.0v higher than stock unless you have some really good cooling.

the 200mv offset only adjusts the vcore on my board. it gives it a little boost so to speak and makes it put out a little more vcore, i haven't seen any difference in the NB or anything else.
