I have rtm875n-606 on AOpen i45gmt-hd, ppl have QFN64 package.
I found out that SL28541 have the same pinout and functions as rtm875n-606

So, to activate OC I have grounded pin 11 through 2k resistor.
btw here arise PLL control registers in SetFSB, which haven't been accessible

now I'm going to test some mods, but mod with FSLB to gnd didn't work for me.
just in case, I have Intel Core X9000 mobile CPU with 800MHz FSB

is there a way to get SETfsb to work on a Toshiba l305 on GL40 chipset with an RTM875T 606? it already supports the same PLL for an HP, however it does not give that PLL as an option in the drop menu when i run it on the Toshiba L305-S5971

Wow - what a document. RTM875t-606 shown uses pin 11 to set TME mode in the 64-pin package. So just need to GND pin 11 to allow setfsb overclocking. They are suggesting that ICS9LPRS365 is pin compatible. Though while they may use the same FSlx pins to set FSB, they may use different internally registers set the FSB via software. setfsb supports RTM875T-587 and RTM876-660, a mix of numbers that looks similar to RTM875t-606 so worth trying those, as well as ICS9LPRS365 with setfsb.

Actually I think nando is right, when you look at the picture of the PLL you see it's a rectangle and has pin 11 as TME:

hi tanjo-15,

you wrote: Hi all.

I tried this mod on my aspire 8920g and it worked a treat.
Just grounded pin 4 of rtm875t-606 to ground.
Then i ran set fsbset and slowly ramped the cpu to 2.6 gig and is still very stable.
My notebook has the t8300 in it.

hope this helps.

where about is the RTM875t-606 postion on the mainboard and what exactly did you do, you connected pin 4 to GND(ground) and did you disconnect anything for pin 4 ? resistor or something else? i want to do this mod also,i have an x9000 (Q174 cpu) and then let s have a look what i can do..

so info or picture wanted Tanjo-15 of you mod.

thanks in advance

i all and thanks i have an hp hdx x16 with rtm875n-606 (square version)
i have grounded pin 11 and i have this now View attachment 77594
nando4 validate i have the tme enable
but when i do this View attachment 77595 my system freeze
i think i have to do another pinmod on pin 17 18??but i dont know how.
thanks for your help

Awesome. My hp Pavilion dv9700t with T9300 (2.5GHz) Penryn has been successfully overclocked to 3.13GHz!

View attachment 46218 View attachment 46219 View attachment 46220 View attachment 46221

Steps:

1. Executed pin mod to TME (pin 4) on RTM875T-606 as illustrated by me here, thanks to moral_hazard, nando4, darnok44 and Darth_nVader as described here. This step actually might not have been strictly necessary, but I'm glad I did it - I'd really like to see if I can get some sort of micro-adjusting FSB tool to work... maybe then I could go even higher than 250MHz FSB!

2. Modified RAM SPD settings with SPDTool 0.63. I used Thaiphoon Burner 6.7.0.0 for advice on changing the latency parameters, and then SPDTool to fix the checksum and burn them into the module. This was all done on an old 1GB Samsung module to test (so if I screwed up, I wouldn't care so much) and now that it's working, I'm going to mod my Crucial (Micron) 2GBx2 sticks -- UPDATE: That didn't work due to the modules' SPD EEPROM being hardware write-protected, so I used two G.Skill 4GB SODIMMS instead, which did work. Details are here.

3. Downloaded custom RTM875T-606 overclocking tool based on SetFSB, found here.

4. Ran the executable OC_RTM875T_250.

5. Voila! T9300 running at 3.13GHz (max temp 70°C) stable enough to run BOINC at 100% CPU for 25 minutes now while I wrote this all up. By the way, IDA is 3.38GHz

is it different for each laptop? or do just ground pin 11?
