Weird overclocking with my Asus sabertooth am3+ board

Hey this board works perfect just i'm trying to push my Athlon II x4 620 more currently at 3.25ghz. As you know the only way to overclock it is to push the board bus speed, this is were i'm getting odd issues my board will overclock to 250 MHz(with ram at 1333) and i put all my settings at 2000 for the north bridge and 2000 for the HT link and i put my ram at 1332.

But when i go to push it more it works perfect went up to 275 and could go higher? you ask then whats the issue well when i go to turn down my ram settings to 1333 or lower it will freeze and lock up or not boot. but when i leave my ram settings alone (making the ram speeds go past 1333) the computer is stable to the point were it boots why is it doing this i have this ram

(G.SKILL Value Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBNT)

Also i can lower my HT and NB frequency's and the board still boots just when i turn down my ram speeds why would it do this?

also could i overclock this ram or would it ruin my ram i do not want bad ram.

why would this board not boot past 250mhz when my ram is turned down but when i leave the ram alone is keeps booting even at 275 and i'll try more if its SAFE.

I usually got things under control when it comes to overclocking but this time i have no idea

Just leave your ram setting alone. Your oc is not pushing your ram too hard. I have 1600 ram and run it at 1691. I have the x58 version of your board. Are upping your volt also. I had to lower my multiplier to 19 the up my ratio to get stable at 4ghz. Good luck..

I know its fine at 1332 but how high could i run it and also why does the board not like it when i turn down my ram speeds

Set the RAM voltage to 1.65V and try again.

I thought i read somewhere that settings the ram up that high from its default 1.5V could not only hurt your ram but your ram controller on the processor as well is this true if not i'll do it

That "problem" is only for Sandy Bridge CPUs, not for AMD.

Saint the PC did not boot with bus at 275mhz with the ram slower then 1333 with a voltage of 1.65V, but the PC booted at 275mhz when the ram speed was left alone the board put my memory at 1469mhz because of the bus overclocking it

Why can i not boot this PC when the ram is turned down
this is so weird i should be able to set the ram settings lower and have it boot(i'm trying to not overclock my ram). i do not know how safe it is to overclock the ram i got. i figure a 5% OC will most likley be fine but what about 10 or 15% if i can get it stable at higher clocks can this break my ram when its overclock past 1333

i also tried setting the ram at 1.5V and booting at speeds lower then 1333 or at near speeds(with a bus higher then 250mhz) to get my processor OC higher
Like i said earler i got G-Skill 1333DDR3 VALUE RAM

Did ram ever break on you after overclocking?

After doing some research barley found anything but it looks like my board might have a issue with the ram divider this is why it wont boot when the ram speed is turned down to low maybe a bios update will fix this

Update to the latest BIOS available and let me know the results

Sadly i'll have to wait because their is only 1 bios version(the first one)

What specs do you have in BIOS for the RAM?

is it because the ram divider is messing with the cas latency,

right now CPU-z says my cas latency is at 8 when it should be 9, also the FSB ratio is at dram 3:8

Set the RAM to the specific times for your RAM as well as the voltage, change the ratio for run your RAM at 1600MHz

Na not worth it. Got my Athlon II X4 620 to boot at 3.8ghz but it cant even get stable at 3.6ghz so i'm calling it a day i had the voltage at 1.55V(the max i'll go) and the max heat went up by 20C(61C). i'll wait to see how good of a Overclocker the 8150 is, then i'll push it to the limit.

This Athlon has lived me well and its not even slow at 3.25Ghz anyways thanks for the help saint at least i know why i could not down clock my ram, it was because of the latency which is fixed it was running at 8 instead of 9 even with my overclock now but its fixed

jdwii, sorry to get here late, but i sorry to tell you that the Bus speed will set automatically with the Sabertooth 990fx, if that is the same board you are using. I have the same board, and the ONLY thing you should need to change is the multiplier. i have my 555BE cranked from 3.2 all the way up to 4.33 with no issues. I have stock cpu voltage at 1.428 and running cool. and saint is totally right as to let your memory run a little slower for stability, as the multiplier will make up for the small drop.
