X51 R2, CPU install help
Hi All,
I am about to change cpu on my X51 R2. I have purchased an i7-4790s - so does it fit straight in (I am sure I have researched enough) but just making sure. Also when fitted, will I just be able to effectively switch machine on and go?
Thank you
Jack

if the CPU is on the list it will fit , Are you asking physically fit or fits and works correctly.(latter I bet)
your spec page clearly stated (read it yet) super clear to me. GEN 4 intel works only.
question 2, simply just turn it on,
well no. (yes if lucky , luck happens)
needs top brand heat sink grease "Shin Etsu best, and rated for 88watts that heat sink if not correct now.
fan plugged back in.
then upgrade BIOS can help if really old BIOS upgrade it. now 1st.
then after CPU swap , inside bios do reset bios to defaults.
just did a OptiPlex this week. gen 4 same.
speedstep

Depends on which motherboard you have.
Dell Alienware X51 R2 Intel LGA 1150 Motherboard
Alienware X51 R2 Launched on 6/3/2013
These I believe are fine. The S models are low power versions 65W which is desired vs 4790K which uses 88W.
Core i5-4460S (Haswell)
Core i5-4130S (Haswell)
Core i7-4770S (Haswell)
Core i7-4790S (Haswell) BX80646I74790S

I would absolutely upgrade to the 330W power Brick if you don't already have that. ( DA330PM111, XM3C3, ADP-330AB B, 5X3NX, 332-1432 )

the S model i am referring to is also a 4th GEN - it just wasn't a standard model - i think this is what I'm finding.

Hi
Still asking for this and would like a yes or no preferably.
Will a i7-4790s work? I've purchased this for power saving.
Currently running an i3-4150, 3.5ghz, 8gb RAM.
I know the 4790 and 4790k are compatible so surely the S will be?
Thank you

Baz1993,
Please do not start multiple threads asking the same question.
"I know the 4790 and 4790K are compatible so surely the S will be?"
Dell cannot answer that conjecture. The retail i7-4790s CPU was NEVER tested/validated by Dell on the 2013 X51 R2. All you can do is test one.
We only tested/validated the following OEM CPU on the 2013 X51 R2 =
9NDTG Haswell i7-4790K, 4.00GHz, 8MB, FSB 1600MHz, 95w
XJWH4 Haswell i7-4790, 3.60GHz, 8MB, FSB 1600MHz, 84w
M6F2X Haswell i7-4770, 3.40GHz, 8MB, FSB 1600MHz, 86w
5GDM4 Haswell i5-4570, 3.20GHz, 6MB, FSB 1600MHz, 86w
NNH7Y Haswell i5-4460, 3.20GHz, 6MB, FSB 1600MHz, 84w
